No matter what problem you encounter, whether it's a grand challenge for humanity or a personal problem of your own, there's an idea out there that can overcome it. And you can find that idea.

When I was a student at MIT, we all shared one computer and it took up a whole building. The computer in your cell phone today is a million times cheaper and a thousand times more powerful. What now fits in your pocket 25 years from now will fit into a blood cell and will again be millions of times more cost effective.

A successful person isn't necessarily better than her less successful peers at solving problems; her pattern-recognition facilities have just learned what problems are worth solving.

When you talk to a human in 2035, you'll be talking to someone that's a combination of biological and non-biological intelligence.

Mobile phones are misnamed. They should be called gateways to human knowledge.

I'm working on artificial intelligence. Actually, natural language understanding, which is to get computers to understand the meaning of documents.
