“The development of full artificial intelligence could spell the end of the human race” – Stephen Hawking.
“AI represents an existential threat to mankind” – Elon Musk.

The real threat, I discover is one of jobs and livelihoods to hundreds of millions in the developed world. More about the current state of the art in AI, and its possible social impacts in my post: The Real Risks of AI.
