He told the BBC:"The development of full artificial intelligence could spell the end of the human race." http://www.bbc.com/news/technology-30290540 Terminator, anyone? Go Blazers

I would have to agree with him. A computer can process information so much more efficiently than any human brain. And the moment that the computer realizes it is a "more powerful alfa being," they will put an end to the race that pollutes and kills for no greater good but themselves.
That is an apt description of artificial intelligence (robots) so maybe they'll just kill themselves.
