It's very hard to predict what kind of uses we'd make of assistants that could read and understand all the information the human race has ever generated. It could be really transformational.

The more we learn about AI and about how the brain works, the more amazing the brain seems. Just the sheer amount of computation it does is truly incredible, especially for a couple of pounds of meat.

I expect that people are going to feel differently about that once they're aware that AI systems can watch through a camera and can, in some sense, understand what it's seeing.

Chess programs don't play chess the way humans play chess. We don't really know how humans play chess, but one of the things we do is spot some opportunity on the chess board toward a move to capture the opponent's queen.

Leg locomotion was, for decades, thought to be an incredibly difficult problem. There has been very, very painstakingly slow progress there, and robots that essentially lumbered along at one step every 15 seconds and occasionally fell over.

The robot is not going to want to be switched off because you've given it a goal to achieve and being switched off is a way of failing - so it will do its best not to be switched off. That's a story that isn't made clear in most movies but it I think is a real issue.

There are lots of companies that are really trying to collect as much information as they can about every single person on the planet because they think its going to be valuable and it probably already is valuable.
