Stephen Hawking is participating in his first-ever reddit AMA. Unlike previous Q&As hosted on the site, Hawking’s will be conducted in two parts. Today, you can submit questions here. Submissions will be selected from by Hawking, who aims to “answer as many of the questions... as possible over the coming weeks.”

“I signed an open letter earlier this year imploring researchers to balance the benefits of AI with the risks,” Hawking explains. “The letter acknowledges that AI might one day help eradicate disease and poverty, but it also puts the onus on scientists at the forefront of this technology to keep the human factor front and center of their innovations.” This morning, Hawking joined many other influential figures in science and technology in signing another letter, this time calling for a ban on “offensive autonomous weapons beyond meaningful human control.”
