SpaceX CEO Elon Musk said that he fears artificial intelligence (AI) will one day take over this world and human beings will be wiped out. He even said that AI is a bigger threat to humanity than nuclear weapons. He said the book Superintelligence is not providing wrong information about what will happen after technology surpasses human intelligence. Musk said that it is not an illusion to think that artificial intelligence could be catastrophic.

Gray Marcus, a professor of cognitive science, said such technologies are not only restricted to things like 'Star Trek' episodes or Philip K. Dick novels.

"It's likely that machines will be smarter than us before the end of the century -- not just at chess or trivia questions but at just about everything, from mathematics and engineering to science and medicine", he wrote. Humanity will be threatened by the ability of computers to program themselves in near future. And they will be able to perform such tasks without taking too much time.

Elon Musk said that it is very important to act proactively before creating artificial intelligence (AI). After reading Nick Bostrom's 'Superintelligence: Paths, Dangers, Strategies', Musk took to Twitter to express his worries over the development of AI.

Science fiction author Isaac Asimov said in 1942 that three things must be taken care of while developing Artificial Intelligence. First, a robot must not hurt a human or allow a human to be hurt and second, a robot must obey human orders unless it is not in the line with the first law. And last, a robot must protect itself as long as there is no breach with the other two laws.
