Thumbs up Artificial Intelligence may kill us all, warns Stephen Hawking



Love Stephen Hawking.. gonna check out his new film tonight.



The Theory of Everything Official Trailer (2014) Stephen Hawking Movie HD






Hawking warns again that Artificial Intelligence could one day destroy humanity, while acknowledging that the early primitive forms of A.I. we currently utilize have been very helpful.
He reiterated his fear of the potential of A.I. to bring about the end of human civilization as we know it in an interview with the BBC. "The development of full artificial intelligence could spell the end of the human race," he warned, as a machine spoke for him.

That kind of A.I. - the primitive technology we use today to overcome obstacles - has been very useful to humanity, Hawking will submit, but he fears for the long term as A.I. becomes increasingly more powerful. Could humans lose their grip on intelligent machines one day?

The pessimistic commentators in this debate cite the potential for artificial intelligence to quickly surpass that of a human being, and could eventually lead to intelligence re-making itself in order to become more and more powerful, or that it may experience a form of "technological evolution" at a pace vastly more rapid than the biological evolution that developed human intelligence.

Such super-smart intelligences may find human affairs totally unimportant, and may even see humanity as a hindrance.

For more optimistic commentators, artificial intelligence may solve problems that are simply beyond us right now and may be for some time yet. It might be a mistake to just assume that an A.I. would have the same evolved survivalist traits of natural species on Earth, or have any reason to become hostile.

Either way, most people do suggest we proceed with caution, but there is even a debate about when we should expect to see such intelligent systems.

Futurists like Ray Kurzweil are predicting A.I. with consciousness in a matter of a few decades, while others believe it could take centuries. Bill Gates, for example, suggested that A.I. on that level will take at least five times longer than Ray Kurzweil thinks it will. Gates was responding to a question on Q&A in Australia, and also said he believed that problems with machine intelligence are solvable, but that we have far more immediately important things to worry about. When asked about the potential for insect-sized drones invading buildings and assassinating people, Gates replied that we already have problems with real insects invading homes and killing people, "it's called malaria."

On the question of whether Artificial Intelligence is even possible, most who chime in on the subject seem to be sure that it is. Why wouldn't they be? Natural intelligence exists, and if nature can create it, then why can't it be reverse engineered?

Stephen Hawking: Artificial intelligence could end up like Skynet


Despite 72-year-old Professor Stephen Hawking just receiving a serious upgrade to his computer-generated speech system, smarter tech, he told the BBC, "The development of full artificial intelligence could spell the end of the human race."

Prof Hawking says the primitive forms of artificial intelligence developed so far have already proved very useful, but he fears the consequences of creating something that can match or surpass humans.

"It would take off on its own, and re-design itself at an ever increasing rate," he said. "Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded."

It?s a bit disturbing when a world-renowned genius sounds in on the AI advancement dilemma and it seems to echo Tesla chief executive Elon Musk?s concerns. Musk has loudly professed his belief that artificial intelligence potentially could be ?more dangerous than nukes.? He also warned AI is ?our biggest existential threat.? Back in October, Musk told an audience at the MIT Aeronautics and Astronautics department?s Centennial Symposium, ?With artificial intelligence we are summoning the demon. In all those stories where there?s the guy with the pentagram and the holy water, it?s like yeah he?s sure he can control the demon. Didn?t work out.?





Nevertheless, at the unveiling of the Hawking?s new ACAT (Assistive Context Aware Toolkit) system in London, Hawking described it as ?life-changing.? Intel has provided Hawking?s computer-based communication system since 1997 and has been ?replacing his computer every two years.? Although it seems nearly unbelievable, his old communication system was older than some college sophomores.

"My old system is more than 20 years old, and I was finding it very difficult to continue to communicate effectively and do the things I love to do every day," Professor Hawking said. He hopes the new system will serve him well ?for the next 20 years.?

Intel redesigned the software Hawking uses; SwiftKey has been working for two years to come up with a new text-prediction system specially designed for Hawking. SwiftKey explained that Hawking ?is only able to communicate by using a small sensor which is activated by a muscle in his cheek. He uses this sensor to ?type? characters and numbers on his keyboard. SwiftKey?s technology has been integrated into his current system so that it can accurately predict whole words, rather than just characters.?

While the new tech should make it easier and faster for Hawking, who would love to play the part of villain in a Bond movie, an exact speed was not given. However, SwiftKey?s SDK team lead Joe Osborne said, ?We estimate that our technology has roughly doubled Professor Hawking?s speech rate to date.?

SwiftKey built a personal ?language model? for Professor Hawking based on his extensive works ? including documents not published in the public domain. The software learns from him to ensure it predicts contextually relevant words. It is also able to analyze the content of the specific book or lecture that he might be working on, further tailoring its predictions and auto-corrections.


Regarding Intel?s new software, Wired reported that when the Intel team that wanted to upgrade Hawking?s human-computer interface first met with Hawking in 2012, ?It took him 20 minutes to write a salutation of about 30 words.? In order to speak, Hawking, who struggles with amyotrophic lateral sclerosis, must first type out the words to be repeated by his synthesized voice. He uses a ?single muscle in his cheek? to write the words, which are then sent to a synthesizer with the voice of ?Perfect Paul." Yet his condition had deteriorated to the point of managing only one word per minute through his communication device.

According to Lama Nachman, principal engineer and project Leader at Intel, it used to take Hawking ?3-4 minutes? to open a document. ?The new system uses a specific icon and takes about 10 seconds,? Nachman told The Guardian.

To use the Intel software, an infrared sensor attached to his glasses allows Hawking to control the software by moving the muscle in his cheek. As he selects letters, predictive text offers him options for completing the word, which speeds up the process. Using these predictions, he now needs to key only about 15-20 percent of the characters in any document. It has doubled his writing speed.
