I think we should be very careful about artificial intelligence. If I were to guess at what our biggest existential threat is, it’s probably that. So we need to be very careful with artificial intelligence. I’m increasingly inclined to think that there should be some regulatory oversight maybe at the national and international level, just to make sure that we don’t do something really foolish. With artificial intelligence, we are summoning the demon. In all those stories where there’s the guy with the pentagram and the holy water and he’s sure that, yeah, he can control the demon. It didn’t work out.
