STORY HIGHLIGHTS
- The smart phone has revolutionized our personal and professional lives by performing as a multimedia computer
- It will continue to change your life as intelligent e-agents become personalized
- Smart phones will evolve in ways that mean they won't need screens -- or big batteries
- They will also increasingly become your wallet, as cash and credit cards become fixtures of the past
Editor's note: Daniel Burrus is a leading futurist on tech trends and innovation. He is the author of six books, including the New York Times best seller Flash Foresight. The opinions expressed in this commentary are solely those of Daniel Burrus.
(CNN) -- The smart phone has revolutionized our
personal and professional lives. More than just a phone, they are
powerful, networked multimedia computers that we carry with us every
day.
Over the next 10 years,
they'll get far more advanced, transforming every business process
including how we sell, communicate, collaborate, train, and educate.
Here are five ways the mobile phone will change your life over the next decade:
Daniel Burrus
1. Your phone will be your personal assistant. The introduction of Apple's Siri
(an intelligent e-agent) gave us a taste of how advanced our phones
could be. As Siri-like agents rapidly advance, they will turn into
personal assistants, searching the web for you and delivering focused,
highly relevant information based on how well it knows you.
The 3D web on your smart phone will be a game-changer for business

Your phone will know your
preferences, likes, and needs. It will automatically compile, present,
and share what's pertinent to you.

Additionally, forget just
talking to a faceless voice. Your intelligent e-agent will have a face
when you are looking at the screen and a personality that you choose.
You'll even see
celebrities and cartoon characters licensing the rights to their digital
likeness and personality, to be used as intelligent e-agents for both
adults and children.
When cellphones were hideous
2. Many smartphones won't have a screen. The traditional smart phone with a screen will not go away, but you will have an option for a screen-less smart phone.
This will be a very
popular and highly adopted smart phone because without the screen, you
get rid of much of the need for a big battery.

Think of the screen-less smart phone like the little piece of jewelry people wore on the old Star Trek TV show. The screen-less smart phone will be touch and voice activated.
When you tap it, you'll
be connected to your intelligent e-agent, which is part of a super
computer in the cloud. Whatever you need, your intelligent e-agent will
be able to verbally give you the information, such as turn-by-turn
directions and your email content
3. Augmented reality will make life easier.
With augmented reality (AR), you use your smartphone camera to see a
live image of a scene in front of you, and an AR app will overlay on the
screen pertinent details about the image.
'I'm the original voice of Siri'
For example, you can
activate the AR app and using your phone's camera, point the camera to a
far off mountain range, and text will overlay onto the image
indicating, for example, the name of the mountains, their elevation and
typical fauna.
How tech helps beat social barriers
The app does this by using the device's GPS, digital compass, and motion sensors to detect where you're pointing the camera.

But it can go much further.
Imagine walking down a
busy shopping district looking for a shoe store that sells a particular
brand. With AR, you could tell your phone what you want and then pan
your phone's camera down the street.
The name of each store
and what brands they sell will appear on your screen, overlaid on the
image of the street. Even better, this technology could also be used
inside large stores to help you find specific items.

4. Your smart phone will have a 3D display and a 3D web browser ... and you won't need special glasses to view it.
Instead of just viewing web pages on your smart phone, you'll be able
to go into environments (or stores or showrooms) and maneuver around in
them, just as you do on devices like the Xbox.
Alternatively, you'll be able to see things sticking out from the screen, again without the special glasses.
The 3D web on your smart phone will be a game-changer for business.
Check e-mails on your watch
5. Your smart phone will increasingly become your wallet. Our wallets are switching from being leather to being phone-based.
Can a headband read your mind?
That means we will use
cash and physical credit cards less often, instead making purchases
using our smart phones. This makes security even more important.
We will use cash and physical credit cards less often, instead making purchases using our smart phones

We already have
near-field communications (NFC) chips taking hold in smart phones. These
chips can help to speed a transaction when you're buying something. You
just get your smart phone close to a cash register that's equipped with
a NFC reader and you can do the transaction.
The use of biometrics
will also increase as an identifier of who you are. This will include
having fingerprint readers like the latest iPhone, audio analysis of
your voice, and facial recognition features in phones.
By using all these things together -- your fingerprint, voice, and face -- your phone will provide a secure payment method.
Read more: The trouble with Apple's Touch ID
This is just a small
sampling of what we'll see for future smart phone technology. All of
these advancements are in their early stages today.
So keep in mind that if it can be done, it will be done. The question is, who will be first?
Mandela’s Candid Opinion Of Nigerian Leaders
Six
years before his death last Thursday, Nelson Mandela took a look at
Nigeria and expressed sadness at the political, economic and social
degeneration of the once touted giant of Africa.He came up with a
damning verdict. He blamed the leaders for abandoning the people.
Mandiba, as he was popularly called by South Africans, accused Nigerian
leaders of betraying their people in a candid interview with Dr Hakeem
Baba Ahmed in 2007.
In the interview conducted in his home, the former South African late hero blasted Nigerian leaders for lack of genuine interest in the success of their people. He lamented the poverty level in Nigeria and the bad education system.
Though he acknowledged Nigeria’s effort in the fight against apartheid, he accused Nigerian leaders of letting their people and Africa down.
Hear Mandela: “You know I am not very happy with Nigeria. I have made that very clear on many occasions. Yes, Nigeria stood by us more than any nation, but you let yourselves down, and Africa and the black race very badly. Your leaders have no respect for their people. They believe that their personal interests are the interests of the people. They take people’s resources and turn it into personal wealth. There is a level of poverty in Nigeria that should be unacceptable. I cannot understand why Nigerians are not more angry than they are.
“What do young Nigerians think about your leaders and their country and Africa? Do you teach them history? Do you have lessons on how your past leaders stood by us and gave us large amounts of money? You know I hear from Angolans and Mozambicans and Zimbabweans how your people opened their hearts and their homes to them. I was in prison then, but we know how your leaders punished western companies who supported apartheid.
“What about the corruption and the crimes? Your elections are like wars. Now, we hear that you cannot be president in Nigeria unless you are Muslim or Christian. Some people tell me your country may break up. Please don’t let it happen.
“Let me tell you what I think you need to do. You should encourage leaders to emerge who will not confuse public office with sources of making personal wealth. Corrupt people do not make good leaders. Then you have to spend a lot of your resources for education.
“Educate children of the poor, so that they can get out of poverty. Poverty does not breed confidence. Only confident people can bring changes. Poor, uneducated people can also bring change, but it will be hijacked by the educated and the wealthy…give young Nigerians good education. Teach them the value of hard work and sacrifice, and discourage them from crimes which are destroying your image as a good people.”

5 ways to preserve your teeth as you age
STORY HIGHLIGHTS
- Regular checkups can be an important part of preserving your teeth
- Wear a night guard if you grind or clench your teeth while sleeping
- Know what dental products are right for you
The good news is, science
and research have taken a front seat in dental education, making
today's dentist savvy on "prevention" dentistry rather than the "drill,
fill and bill" mentality of decades ago.
Things like adhesive
dentistry, recalcification and dental implants have given dentists more
options. But for many patients, it's a lot of information to process.
Here are five ways you can ensure that you hang on to your teeth as you age:
Dr. Michael Apa
Educate yourself on dental care
Dentistry today has taken
a much more conservative approach. But it can be hard to know what your
options are. Here are some key points that you should know about dental
treatment.
• Small cavities can be
recalcified. Strong doses of fluoride, or something called MI Paste,
applied directly to small cavities can actually recalcify or rebuild the
enamel, removing the need for a filling.
That said, the key to
recalcification is early detection. Regular dental visits and staying on
top of your annual X-rays are crucial to early detection.
• Fillings, crowns or
any dental restoration should be replaced or heavily scrutinized every
eight years, as recommended by the American Dental Association.
Some patients are of the
"if it ain't broke, don't fix it" era. But the reasoning behind this
advice is to eliminate the spread of recurrent cavities that lurk under
dental restorations.
The longer you wait to
replace dental restorations, the more problems you can run into. If the
decay spreads undetected, it may eat up too much healthy tooth structure
and need the support of a crown or reach the nerve and need a root
canal.
• Make sure your
children are getting fluoride treatments until at least the age of 15.
Kids, especially, consume a lot of sugar, which breaks down into a
biproduct of acid that erodes teeth, quickly causing cavities. Fluoride
is a great treatment in rebuilding enamel and neutralizing those acids.
Use an electric toothbrush
In dentistry, the
electric toothbrush has been one of the biggest advances in home dental
care. Ninety-nine percent of patients don't really know how to brush
with a manual brush and, more important, don't brush for the full two
minutes needed.
Electric toothbrushes
remove the confusion and have a timer to ensure that the full brushing
is done at each session. Improper brushing can lead to plaque buildup,
swollen gums, cavities and overall poor oral health. The sonic brushes
remove plaque and get into hard-to-reach places like in between teeth
and under the gums to ensure a healthy mouth.
If you grind or clench, wear a night guard
Grinders can wear away a
millimeter of tooth structure per year if undiagnosed. Clenchers may
not see any immediate signs of wear on their teeth, but the pressure
that clenching puts on your teeth is destructive. It slowly breaks down
the supporting bone around the teeth, leading to gum recession, bone
loss and inevitably tooth loss.
If you feel that you may
fall into either of these categories, you should be wearing a night
guard. It may not be sexy, but it's much sexier than missing teeth.
Know what oral hygiene regimen is right for you
Today, there has been a
lot of money and research into better oral care products. But understand
that there is an actual regimen of toothpaste, mouth rinse and
"extra-care" products that's right for you.
The first step is
defining what "type" of patient you are. I like to break it down into
four basic types: cavity-prone, sensitive, stainers and those with bad
gums.
You can ask your dentist
which category you fall into. Each product in the sea of dental
products in the drugstore has key ingredients tailored for each category
of patient. Using the right oral care products can make a big
difference in the longevity of your teeth.
Choose the right dentist
Fortunately -- or
unfortunately -- your dentist has a lot to do with the preservation of
your teeth. Make sure your dentist is up on all current research and his
office is updated and state-of-the-art, but most important, make sure
your dentist is taking time and looking after you. It sounds simple, but
it's probably the most important item on your checklist.
Nelson Mandela of South Africa Is Dead!
Nelson Mandela, the prisoner-turned-president who helped end apartheid in S. Africa, has died, Zuma confirms. He was 95.
(CNN) -- Nelson Mandela, the revered statesman who
emerged from prison after 27 years to lead South Africa out of decades
of apartheid, has died, South African President Jacob Zuma announced
late Thursday. He was 95.
STORY HIGHLIGHTS
- In a nation healing from the scars of apartheid, Nelson Mandela became the moral compass
- With bouts of illness, the anti-apartheid icon faded from the limelight in recent years
- Mandela spent 27 years in prison; 18 of them were on Robben Island
The former president
battled health issues in recent months, including a recurring lung
infection that led to numerous hospitalizations.
With advancing age and
bouts of illness, Mandela retreated to a quiet life at his boyhood home
in the nation's Eastern Cape Province, where he said he was most at
peace.
Despite rare public appearances, he held a special place in the nation's consciousness.
A hero to blacks and whites
In a nation healing from the scars of apartheid, Mandela became a moral compass.
Look back at Mandela's early years |
1990: Mandela released from prison |
1994: Mandela takes oath of office |
His defiance of white
minority rule and incarceration for fighting against segregation focused
the world's attention on apartheid, the legalized racial segregation
enforced by the South African government until 1994.
In his lifetime, he was a
man of complexities. He went from a militant freedom fighter, to a
prisoner, to a unifying figure, to an elder statesman.
Years after his 1999
retirement from the presidency, Mandela was considered the ideal head of
state. He became a yardstick for African leaders, who consistently fell
short when measured against him.
Warm, lanky and
charismatic in his silk, earth-toned dashikis, he was quick to admit to
his shortcomings, endearing him further in a culture in which leaders
rarely do.
His steely gaze disarmed opponents. So did his flashy smile.
Former South African
President F.W. de Klerk, who was awarded the Nobel Peace Prize with
Mandela in 1993 for transitioning the nation from a system of racial
segregation, described their first meeting.
"I had read, of course, everything I could read about him beforehand. I was well-briefed," he said last year.
"I was impressed,
however, by how tall he was. By the ramrod straightness of his stature,
and realized that this is a very special man. He had an aura around him.
He's truly a very dignified and a very admirable person."
For many South Africans,
he was simply Madiba, his traditional clan name. Others affectionately
called him Tata, the Xhosa word for father.
A nation on edge
Mandela last appeared in
public during the 2010 World Cup hosted by South Africa. His absences
from the limelight and frequent hospitalizations left the nation on
edge, prompting Zuma to reassure citizens every time he fell sick.
"Mandela is woven into
the fabric of the country and the world," said Ayo Johnson, director of
Viewpoint Africa, which sells content about the continent to media
outlets.
When he was around, South Africans had faith that their leaders would live up to the nation's ideals, according to Johnson.
"He was a father figure,
elder statesman and global ambassador," Johnson said. "He was the
guarantee, almost like an insurance policy, that South Africa's young
democracy and its leaders will pursue the nation's best interests."
There are telling nuggets of Mandela's character in the many autobiographies about him.
An unmovable stubbornness. A quick, easy smile. An even quicker frown when accosted with a discussion he wanted no part of.
War averted
Despite chronic
political violence in the years preceding the vote that put him in
office in 1994, South Africa avoided a full-fledged civil war in its
transition from apartheid to multiparty democracy. The peace was due in
large part to the leadership and vision of Mandela and de Klerk.
"We were expected by the
world to self-destruct in the bloodiest civil war along racial
grounds," Mandela said during a 2004 celebration to mark a decade of
democracy in South Africa.
"Not only did we avert
such racial conflagration, we created amongst ourselves one of the most
exemplary and progressive nonracial and nonsexist democratic orders in
the contemporary world."
Mandela represented a
new breed of African liberation leaders, breaking from others of his era
such as Robert Mugabe by serving one term.
In neighboring Zimbabwe,
Mugabe has been president since 1987. A lot of African leaders
overstayed their welcomes and remained in office for years, sometimes
decades, making Mandela an anomaly.
But he was not always popular in world capitals.
Until 2008, the United
States had placed him and other members of the African National Congress
on its terror list because of their militant fight against the
apartheid regime.
Humble beginnings
Rolihlahla Mandela
started his journey in the tiny village of Mvezo, in the hills of the
Eastern Cape, where he was born on July 18, 1918. His teacher later
named him Nelson as part of a custom to give all schoolchildren
Christian names.
His father died when he was 9, and the local tribal chief took him in and educated him.
Mandela attended school
in rural Qunu, where he retreated in 2011 before returning to
Johannesburg and later Pretoria to be near medical facilities.
He briefly attended
University College of Fort Hare but was expelled after taking part in a
protest with Oliver Tambo, with whom he later operated the nation's
first black law firm.
In subsequent years, he
completed a bachelor's degree through correspondence courses and studied
law at the University of Witwatersrand in Johannesburg, but left
without graduating in 1948.
Four years before he
left the university, he helped form the youth league of the African
National Congress, hoping to transform the organization into a more
radical movement. He was dissatisfied with the ANC and its old-guard
politics.
And so began Mandela's civil disobedience and lifelong commitment to breaking the shackles of segregation in South Africa.
Escalating trouble
In 1956, Mandela and
dozens of other political activists were charged with high treason for
activities against the government. His trial lasted five years, but he
was ultimately acquitted.
Meanwhile, the fight for equality got bloodier.
Four years after his
treason charges, police shot 69 unarmed black protesters in Sharpeville
township as they demonstrated outside a station. The Sharpeville
Massacre was condemned worldwide, and it spurred Mandela to take a more
militant tone in the fight against apartheid.
The South African
government outlawed the ANC after the massacre, and an angry Mandela
went underground to form a new military wing of the organization.
"There are many people
who feel that it is useless and futile for us to continue talking peace
and nonviolence against a government whose reply is only savage attacks
on an unarmed and defenseless people," Mandela said during his time on
the run.
During that period, he
left South Africa and secretly traveled under a fake name. The press
nicknamed him "the Black Pimpernel" because of his police evasion
tactics.
Militant resistance
The African National
Congress heeded calls for stronger action against the apartheid regime,
and Mandela helped launch an armed wing to attack government symbols,
including post offices and offices.
The armed struggle was a defense mechanism against government violence, he said.
"My people, Africans,
are turning to deliberate acts of violence and of force against the
government, in order to persuade the government, in the only language
which this government shows by its own behavior that it understands,"
Mandela said during a hearing in 1962.
"If there is no dawning
of sanity on the part of the government -- ultimately, the dispute
between the government and my people will finish up by being settled in
violence and by force. "
The campaign of violence against the state resulted in civilian casualties.
Long imprisonment
In 1962, Mandela
secretly received military training in Morocco and Ethiopia. When he
returned home later that year, he was arrested and charged with illegal
exit of the country and incitement to strike.
Mandela represented
himself at the trial and was briefly imprisoned before being returned to
court. In 1964, after the famous Rivonia trial, he was sentenced to
life in prison for sabotage and conspiracy to overthrow the government.
At the trial, instead of
testifying, he opted to give a speech that was more than four hours
long, and ended with a defiant statement.
"I have fought against
white domination, and I have fought against black domination," he said.
"I have cherished the ideal of a democratic and free society in which
all persons live together in harmony and with equal opportunities. It is
an ideal which I hope to live for and to achieve. But if needs be, it
is an ideal for which I am prepared to die."
His next stop was the
Robben Island prison, where he spent 18 of his 27 years in detention. He
described his early days there as harsh.
"There was a lot of physical abuse, and many of my colleagues went through that humiliation," he said.
One of those colleagues
was Khehla Shubane, 57, who was imprisoned in Robben Island during
Mandela's last years there. Though they were in different sections of
the prison, he said, Mandela was a towering figure.
"He demanded better
rights for us all in prison. The right to get more letters, get
newspapers, listen to the radio, better food, right to study," Shubane
said. "It may not sound like much to the outside world, but when you are
in prison, that's all you have."
And Mandela's khaki prison pants, he said, were always crisp and ironed.
"Most of us chaps were
lazy, we would hang our clothes out to dry and wear them with creases.
We were in a prison, we didn't care. But Mandela, every time I saw him,
he looked sharp."
After 18 years, he was transferred to other prisons, where he experienced better conditions until he was freed in 1990.
Months before his release, he obtained a bachelor's in law in absentia from the University of South Africa.
Calls for release
His freedom followed
years of an international outcry led by Winnie Mandela, a social worker
whom he married in 1958, three months after divorcing his first wife.
Mandela was banned from reading newspapers, but his wife provided a link to the outside world.
She told him of the growing calls for his release and updated him on the fight against apartheid.
World pressure mounted
to free Mandela with the imposition of political, economic and sporting
sanctions, and the white minority government became more isolated.
In 1988 at age 70,
Mandela was hospitalized with tuberculosis, a disease whose effects
plagued him until the day he died. He recovered and was sent to a
minimum security prison farm, where he was given his own quarters and
could receive additional visitors.
Among them, in an unprecedented meeting, was South Africa's president, P.W. Botha.
Change was in the air.
When Botha's successor, de Klerk, took over, he pledged to negotiate an end to apartheid.
Free at last
On February 11, 1990, Mandela walked out of prison to thunderous applause, his clenched right fist raised above his head.
Still as upright and proud, he would say, as the day he walked into prison nearly three decades earlier.
"As I walked out the
door toward the gate that would lead to my freedom, I knew if I didn't
leave my bitterness and hatred behind, I'd still be in prison," he said
at the time.
He reassured ANC
supporters that his release was not part of a government deal and
informed whites that he intended to work toward reconciliation.
Four years after his release, in South Africa's first multiracial elections, he became the nation's first black president.
"The day he was inducted
as president, we stood on the terraces of the Union Building," de Klerk
remembered years later. "He took my hand and lifted it up. He put his
arm around me, and we showed a unity that resounded through South Africa
and the world."
Broken marriage, then love
His union to Winnie
Mandela, however, did not have such a happy ending. They officially
divorced in 1996 after several years of separation.
For the two, it was a
fiery love story, derailed by his ambition to end apartheid. During his
time in prison, Mandela wrote his wife long letters, expressing his
guilt at putting political activism before family. Before the
separation, Winnie Mandela was implicated in violence, including a
conviction for being an accessory to assault in the death of a teenage
township activist.
Mandela found love again two years after the divorce.
On his 80th birthday, he married Graca Machel, the widow of former Mozambique president, Samora Machel.
Only three of Mandela's children are still alive. He has 17 grandchildren and 12 great-grandchildren
Symbolic rugby
South Africa's fight for
reconciliation was epitomized at the 1995 rugby World Cup Final in
Johannesburg, when it played heavily favored New Zealand.
As the dominant sport of
white Afrikaners, rugby was reviled by blacks in South Africa. They
often cheered for rivals playing their national team.
Mandela's deft use of
the national team to heal South Africa was captured in director Clint
Eastwood's 2009 feature film "Invictus," starring Morgan Freeman as
Mandela and Matt Damon as Francois Pienaar, the white South African
captain of the rugby team.
Before the real-life
game, Mandela walked onto the pitch, wearing a green-and-gold South
African jersey bearing Pienaar's number on the back.
"I will never forget the
goosebumps that stood on my arms when he walked out onto the pitch
before the game started," said Rory Steyn, his bodyguard for most of his
presidency.
"That crowd, which was
almost exclusively white ... started to chant his name. That one act of
putting on a No. 6 jersey did more than any other statement in bringing
white South Africans and Afrikaners on side with new South Africa."
During his presidency,
Mandela established the Truth and Reconciliation Commission to
investigate human rights abuses during apartheid. He also introduced
housing, education and economic development initiatives designed to
improve the living standards of the black majority.
A promise honored
In 1999, Mandela did not
seek a second term as president, keeping his promise to serve only one
term. Thabo Mbeki succeeded him in June of the same year.
After leaving the
presidency, he retired from active politics, but remained in the public
eye, championing causes such as human rights, world peace and the fight
against AIDS.
It was a decision born
of tragedy: His only surviving son, Makgatho Mandela, died of AIDS at
age 55 in 2005. Another son, Madiba Thembekile, was killed in a car
crash in 1969.
Mandela's 90th birthday
party in London's Hyde Park was dedicated to HIV awareness and
prevention, and was titled 46664, his prison number on Robben Island.
A resounding voice
Mandela continued to be a voice for developing nations.
He criticized U.S.
President George W. Bush for launching the 2003 war against Iraq, and
accused the United States of "wanting to plunge the world into a
Holocaust."
And as he was acclaimed
as the force behind ending apartheid, he made it clear he was only one
of many who helped transform South Africa into a democracy.
In 2004, a few weeks before he turned 86, he announced his retirement from public life to spend more time with his loved ones.
"Don't call me, I'll call you," he said as he stepped away from his hectic schedule.
'Like a boy of 15'
But there was a big treat in store for the avid sportsman.
When South Africa was awarded the 2010 football World Cup, Mandela said he felt "like a boy of 15."
In July that year, he
beamed and waved at fans during the final of the tournament in
Johannesburg's Soccer City. It was his last public appearance.
"I would like to be
remembered not as anyone unique or special, but as part of a great team
in this country that has struggled for many years, for decades and even
centuries," he said. "The greatest glory of living lies not in never
falling, but in rising every time you fall."

No tech bubble here
Market analysts say this Nasdaq run-up is nothing like the tech bubble of 13 years ago.
NEW YORK (CNNMoney)
The tech-heavy Nasdaq index recently topped 4,000 ... a level it hasn't reached since the dot-com boom days of 2000. But this run-up is nothing like the tech bubble of 13 years ago.
It makes sense that benchmarks like the Nasdaq at 4,000 could reignite bubble fears. It comes after the recent string of successful initial public offerings from unprofitable companies like Twitter (TWTR), and reports of startup Snapchat turning down a $4 billion buyout -- despite bringing in no revenue."Anytime you have a substantial run in an asset -- especially one like the Nasdaq ... you can't help but ask the [bubble] questions," said Drew Nordlicht, managing director at asset management firm HighTower Advisors. "But there are big divergences between now and the tech bubble of 2000."
2000 vs. 2013: The biggest difference between now and then: The hype in 2013 is fairly muted compared with the dot-com heyday.
Sure, Facebook's (FB, Fortune 500) IPO may have been overhyped, and select startups will continue to raise money at seemingly astronomical valuations. But analysts insist the exuberance level doesn't even come close to the old days.
"In 2000, people said the [dot-com boom] was on par with the Industrial Revolution -- we were going to be living in one of those sci-fi movies," Nordlicht said. "We don't have that level of a mass fever pitch today."
Todd Salamone, senior research VP at Schaefer's Investment Research, agreed.
"There was a 'sky's the limit' mentality in 2000, in terms of revolutionary technology leading to productivity enhancements," Salamone said. "There was no prediction that was too high. Today there is a lot more hand-wringing, more caution."
By the numbers: It's not just about irrational excitement: Tech company valuations this time around simply don't rival those of 2000.
Back in 2000, a person would hardly blink an eye at a company like Cisco (CSCO, Fortune 500) trading at 66 times earnings estimates for the coming year, said Nordlicht, the HighTower managing director.
These days, Cisco's price-to-earnings ratio is hovering below 12 -- near that of mighty Apple (AAPL, Fortune 500). Even Google (GOOG, Fortune 500), which has generally reported strong earnings this year and is poised to overtake Exxon Mobil (XOM, Fortune 500) in market capitalization, is trading at 24 times earnings expectations for next year.
While the Nasdaq does have outliers like Netflix (NFLX) trading at more than 200 times earnings, such high ratios aren't the norm -- and the broader index is much more grounded in reality than 13 years ago.
"These ratios aren't levels that have defined peaks in the past," said Salaome, the Schaefer's senior research VP. "Far from it."
Price-to-earnings ratios soared so high in 2000 because "people were buying companies based on future prospects -- where you expected them to be a in a decade," Nordlicht said. "You don't see that today. Even if people aren't demanding profitability right now, they want to see a road that leads to profit."

A slower rise to 4,000: Looking at the Nasdaq's overall gains, Salamone pointed out the 1999-2000 run-up was "parabolic": The index hit 3,000 in November 1999 and topped 4,000 the following month, before reaching a high above 5,000 in March 2000.
"Today's move is not what I would call parabolic," Salamone said. This time around, the Nasdaq took nearly a year to jump from 3,000 to 4,000.
What's more, the Nasdaq has risen along an overall 2013 bull market, on stronger macroeconomic conditions: the Federal Reserve's bond-buying program, the overall improving economy and low earnings expectations. The Nasdaq's 32% gain so far in 2013 is only six percentage points above that of the S&P (SPX) 500 index, and ten points above the Dow's (INDU) jump.
Startups will continue to raise gobs of cash, and select tech sectors like social-media stocks may get rather frothy. But the established techs in the Nasdaq -- and the index's gain -- aren't where to look if you're trying to prove a bubble.
In fact, Salamone thinks the memory of 2000 is still too fresh to let the excitement soar into bubbly exuberance.
"In 2000, everybody looked back and was shocked by how badly they were burned," he said. "Now everyone's afraid of that happening again -- and it's hard to have a bubble when everybody fears a bubble."
Mutant fungus croaks frog named after Darwin
STORY HIGHLIGHTS
- Aggressive fungus wiping out amphibians worldwide
- It has made some species extinct, including a frog species named for Charles Darwin
- There is another Darwin frog that is now endangered
- The male of the species sort of gets pregnant, the way seahorses do
Now be glad you're not a
newt, a salamander or a frog -- particularly two species of frogs called
Darwin's frogs named after Charles Darwin. Because one of them is now
extinct and the other endangered, scientists say.
A hyper-aggressive fungus
with some changed up DNA is infecting and killing amphibians, and has
done in hordes of these frogs, according to a new study published last week in the scientific journal PLOS ONE.
One of the species,
Rhinoderma rufum, was last seen in the wild in 1980. Its close cousin,
Rhinoderma darwinii, which Darwin first discovered on his sailing voyage
around the world in the 1830s, is endangered.
A few groups of them
still live in temperate forests in Chile, in South America, where Darwin
found them back then. But now, they are just hanging on.
What the disease has not done to kill them, human activity, including tree farming, has.
In addition to the
distinction of bearing the name of the author of the theory of
evolution, the frogs are also the only vertebrates aside from sea
horses, in which the male of the species sort of gets pregnant.
"The males care for their
young by incubating them in their vocal sacs for at least part of their
development," the study says. The result is a baby bump.
The frogs represent
merely canaries in the mine as far as the disease is concerned.
Virtually all amphibians can catch it. The fungus -- Batrachochytrium dendrobatidis in scientific lingo -- causes a nasty infection.
It is called
chytridiomycosis, and scientists have said that it is "the worst
infectious disease ever recorded among vertebrates in terms of the
number of species impacted and its propensity to drive them to
extinction."
And the fungus is genetically flexible. There are many strains of it, with the possibility of new ones popping up.
The most virulent one has recombinant DNA.
It's basically a mutant.
Report linking Bitcoin and Silk Road retracted
After suggesting earlier this week that a link existed between the creators of Silk Road and Bitcoin, two Israeli computer researchers have retracted their report.
The academic report had suggested that Satoshi Nakamoto, the yet-unidentified creator of virtual currency Bitcoin, gave an unusually large sum of money to someone known as Dread Pirate Roberts, founder of the online black market Silk Road."Unless I have split personalities and this is Fight Club, I definitely am not Satoshi Nakamoto," Trammell recently wrote on his blog.

The Weizmann Science Institute researchers, Dorit Ron and Adi Shamir, admitted that they were wrong, even though they said the link was merely a theory.
"Now that a better explanation exists, we no longer believe that the [account] belonged to Satoshi," the researchers said in an email.
In his blog, Trammell denied having any connection to Silk Road, saying he made the large transfer of money to himself. That wouldn't be odd, given that Bitcoin users often keep multiple digital wallets.
But the man that federal authorities have arrested and accused of launching Silk Road, Ross Ulbricht, is from Austin too. Given the folklore surrounding Bitcoin and Silk Road, get ready for rumors that Trammell is Satoshi hiding in plain sight.

Art of Movement is CNN's monthly show exploring the latest innovations in art, culture, science and technology.
(CNN) -- There's a lot to be said for determination.
Two years ago, a contraption that looked a bit like a bouncy ball
attached to a clothesline, took flight in a pioneering experiment in the
German countryside.
A YouTube clip of a man flying the electric "Multicopter"
attracted over 8 million hits, with comments ranging from: "AMAZING
MACHINE!" to "Not sure you could pay me enough to sit in the middle of
flying blenders bolted together."
Regardless, the three
German engineers behind the baffling creation plowed ahead with their
dream of making an electric helicopter. Last week it paid off.
There wasn't a bouncy ball in sight as the slick white "Volocopter" took to the air for the first time, quietly hovering 20 meters high, while its ecstatic creators cheered below.
Featuring 18 propellers
on a lightweight carbon frame, the futuristic copter -- which has been
around €4 million ($5.4 million) in the making -- could change the way
we commute forever.
"What we're looking at
now, is in the future where everyone is traveling not by car, but by
some kind of aircraft," explained Stephan Wolf, co-chief executive of e-volo, the company behind the remarkable flying machine.
"Normal helicopters are
very hard to fly. But we thought 'what if you could have a helicopter
that is easy for the pilot to fly, and cheap compared to other
aircraft?'"
Clever copter
Powered by a 100
kilogram battery, the two-passenger Volocopter can travel at least 70
kilometers per hour, recently making its first remote-controlled flight
in a hanger in Karlsruhe, southwest Germany.
The chopper weighs just
300 kilograms in total. One limitation is that it currently only has
enough power to fly for 20 minutes -- though designers are looking at
ways of increasing this, or introducing a hybrid engine.

Many small rotors --
attached to a 10-meter wide circular frame -- also help the eco-friendly
machine hover more easily than other helicopters.
"If you let the joystick
go, the Volocopter will just hover in the current position, so there's
nothing the pilot has to do," said Wolf.
"But if you do that in another helicopter it will crash immediately."
Reimagining the city
Indeed, the Volocopter's
simplicity sets it apart from other helicopters, and its creators hope
in the future commuters will be able to take their electric aircraft to
work, instead of languishing in gridlocked cars below.
The European Union
is already looking at ways personal aerial vehicles (PAVs) could
revolutionize urban spaces. It might sound like a scene from the
Jetsons, but a city where flying machines replace cars isn't as far off
as it seems.
"The most helicopters in the world are in Sao Paulo, Brazil,"
explained Wolf. "They have several thousand movements per day because
the streets are congested and everyone who can afford it is taking the
helicopter to go from one building to the next.
"You can imagine this
happening in a big city in Germany. And already we've been approached by
several companies who'd like to do it, maybe with landing pads on
buildings."
The team hopes to sell
its first Volocopter by 2015, with each machine setting you back
€250,000 ($338,000). They're now on the lookout for further funding to develop their unique design.
Think big
Maybe you need to go up in the air, to solve transportation problems
Stephan Wolf, co-chief executive, e-volo

It's a long way from the first awkward-looking Multicopter test flight in 2011.
Even more impressive,
considering Wolf himself was a computer software engineer for 25 years
before turning his attention to futuristic flying machines -- "I was
dreaming of building a helicopter since I was a child," he said.
Then there's the other
e-volo founders -- Thomas Senkal, a former physicist, and Alexander
Zosel, who managed a disco for almost 10 years, who also got on board
the pioneering project.
"I think everyone wants
to fly," said Wolf. "Helicopters are very expensive and people think
maybe this is a way to be a pilot themselves.
"In 20 or 30 years from
now there will be even more cities with millions more people living in
them and transportation will be a big problem. Maybe you need to go up
in the air to solve these problems."
Next-generation video game consoles: Which should you buy?
STORY HIGHLIGHTS
- Console gamers have lots of choices this holiday season
- The PlayStation 4 has dynamic graphics, improved controllers and middle-of-pack pricing
- Xbox One is an entertainment hub with a smooth interface
- Wii U is most affordable and has a year's worth of games to choose from
Whether on the hunt for
yourself or, more likely, looking for a gift for a friend or family
member, the decision isn't an easy one. Both Sony's PlayStation 4 and Microsoft's Xbox One
hit stores in the past week or so, and both are off to huge starts.
Each sold more than 1 million units in their first 24 hours.
Nintendo -- the third player in console gaming's Big Three -- has its year-old "next generation" console, the Wii U, to consider as well.
To be sure, there are
lots of factors to consider when making a choice. But if you're trying
to decide which box should end up under the tree, take a look at some
thoughts what we see as a big advantage for each console.
You'll want a PlayStation 4 if ...
you want a solid social gaming machine offering intricate, beautiful games that players can share easily with friends.
The next generation of
consoles has more power than its predecessors, so games look more robust
and offer expanded environments of play and more intricate detail. In
"Knack," the PS4's power is on display when hundreds of tiny relics form
in a mystical creature with animation that's near-Pixar quality.
Next-gen graphics, improved controllers and social sharing suggest the PlayStation 4.
The DualShock 4
controller contains new features that work very well for some games. The
touchpad offers a new way to interface with gameplay. In "Killzone:
Shadow Fall," a swipe across the pad activates different features for
your robotic companion.
A social sharing button
directly on the controller allows players to let others see their
accomplishments. Video clips, screenshots and direct broadcasts are
available through Facebook, Twitter, Twitch and Ustream right out of the
box.
It also should be
mentioned that at $399, the PS4 is $100 cheaper than the rival Xbox One.
When disc games are $60 and download games run $15, the money saved
could be used to get the content you want.
You'll want an Xbox One if ...
you are in the market
for a multimedia machine that can multitask and switch between games,
movies, music and applications quickly and seamlessly.
Easily the best thing
about the X1 (so far) is how quickly the new interface switches from one
application to another with just a voice command (via an improved
Kinect).
Microsoft has made the Xbox One much more than a gaming device with entertainment and other apps.
The hands-free controller not only works for games, it changes the channels on your TV, serves up movie content or uses the Snap function to do two things at once.
Snap allows for
split-screen multitasking on the fly. Say you are watching the local NFL
game through the X1, but you want to know how your fantasy football
team is doing. Snap brings up a Web browser in a side window to let you
access your online team without missing a handoff in the game you're
watching.
And it is all done with
voice command through Kinect. It can recognize six voices and learns the
games, shows and apps that each of those people likes. Of course, it
also can create a new power struggle for the remote control as opposing
viewers scream instructions to the console.
The X1, which costs
$499, has an amazing suite of entertainment choices with partners like
Hulu Plus, Netflix, YouTube and more. Microsoft wants to offer people as
many television, movie and music choices as possible, and content
providers are signing up.
You'll want a Wii U if ...
you want a wider selection of games to play now and at a price that won't blow away your entire holiday budget.
Lest we forget, the Nintendo Wii U is also a next-generation gaming console.
The Wii U costs just $299 and has a year's worth of games to choose from.
It has the advantage of
having been on the market for more than a year. Developers have used
that time to produce quality games for all age groups. Titles like
"Super Mario 3D World," "Pikmin 3" and "The Legend of Zelda: Wind Waker
HD" -- along with Wii U versions of many highly sought-after third-party
titles -- make the console more attractive compared with the limited
number of titles available on the new PlayStation and Xbox.
And the Wii U is
backward-compatible, meaning any Wii controllers or games you owned
before upgrading to the next-gen box still work on the Wii U. The other
next-gen consoles won't let you play your older games and require new
controllers to use them.
And this might be a big
factor for some: Nintendo recently cut the price of the Wii U to $299,
making it $100 less than the PS4 and $200 less than the X1.
For what's been promoted
as as a family-friendly console, that price difference could be
important as holiday spending gets tighter. Plus, the extra money can be
used to buy games.

STORY HIGHLIGHTS
- Could flying robots invade the market for presents this Christmas?
- Toys 'R' Us names remote controlled flying toys as "top gifts" this year
- Both novelty and high tech devices are becoming increasingly affordable
Both international toy store Toys 'R' Us and the UK's Toy Retailers Association
have named remote control flying toys among their "top toys" for
Christmas 2013 -- and that's just the beginning of the flying robot
invasion. Aerial bots of all sizes -- from miniature flying fairies to
full-scale surveillance aircraft -- could be appearing under Christmas
trees come December 25.
It's evidence that the high tech materials and components developed for complex flying robots are filtering down creatively to the new world of "civilian Unmanned Aerial Vehicles."
It wasn't long ago that easily controlled multifunctional quadcopters were only seen in the hands of tech university researchers
and military specialists. Now, cheap, lightweight motors and
stability-providing gyroscopes are available to anyone, opening up
flying robot technology to the world of toys, as well as providing new
ways for shutterbugs to make home movies and shoot aerial photos.
Check out the slideshow
above to see some of the amazing flying robots that are available for
kids and adults alike. And consider giving Rudolph a break this year by
giving a gift that can make its own way down the chimney.
