Could Artificial Intelligence Threaten Human Existence?

#artificialintelligence 

Artificial intelligence has always been an interesting subject to discuss especially among fiction writers. Thousands of artificial intelligence applications have been used for years in almost every industry: scientific discovery, medical diagnosis, robot control, stock trading, remote sensing, and even toys. Stephen Hawking says that the development of full artificial intelligence could spell the end of the human race. But, a lot of scientist don't agree with him. They say artificial intelligence could damage society if and only it built or used incorrectly.
