Theoretical physicist Stephen Hawking may have passed away Wednesday morning, but the legacy he left will be felt for many years to come.

Once the news of his death had reached Reddit, a thread about the legendary scientist was started on the r/science board. One of the links re-shared at the top was from Hawking's Reddit AMA, which took place two years ago.

Many of his answers, which you can read in full in the thread, discuss the risks associated with artificial intelligence.

On the evolution of AI

On the need for 'beneficial intelligence'

On the possibility of AI exceeding human intelligence

On the reason why AI could be a threat to humans

On 'technological unemployment'

Finally, as a bonus, here's his favourite film, song, and the last thing he found hilarious.
