People all over the world are mourning the death of legendary physicist Stephen Hawking, who passed away at his home in Cambridge on Wednesday, March 14th. The world-renowned scientist was hailed for his research on black holes and relativity, and for helping us better understand the universe and our place in it.

Hawking literally defied the odds by outliving his life expectancy by more than half a century. Following his diagnosis of amyotrophic lateral sclerosis (ALS) at the age of 21, doctors told him it was unlikely he would live more than a couple of years. Yet Hawking was 76 when he died, and had continued working long after his life-changing diagnosis, furthering his iconic research on black holes and sharing his awe-inspiring theories on the cosmos.

In the wake of Stephen Hawking’s death, tributes from celebrities like Eddie Redmayne — who won an Oscar for his portrayal of Hawking in 2014’s The Theory of Everything — and shares of his most inspirational quotes quickly began popping up on social media.

But something in particular that caught our eye was found on Mashable, which shared Hawking’s last comments on Reddit during his AMA in 2016. The discussion focused on artificial intelligence, and Hawking’s answers are just another example of his amazing intellect.

Here’s some of what Stephen Hawking had to say about the risks of AI.

One Reddit user asked: “How smart do you think the human race can make AI, while ensuring that it doesn’t surpass them in intelligence?”

Another Reddit user wanted to know what Stephen Hawking thought about the possibility of AI becoming a threat to humans.
