As leaders, it is incumbent on all of us to make sure we are building a world in which every individual has an opportunity to thrive. Understanding what AI can do and how it fits into your strategy is the beginning, not the end, of that process.

AI has been making tremendous progress in machine translation, self-driving cars, etc. Basically, all the progress I see is in specialised intelligence. It might be hundreds or thousands of years or, if there is an unexpected breakthrough, decades.

Deep-learning will transform every single industry. Healthcare and transportation will be transformed by deep-learning. I want to live in an AI-powered society. When anyone goes to see a doctor, I want AI to help that doctor provide higher quality and lower cost medical service. I want every five-year-old to have a personalised tutor.

Despite all the hype and excitement about AI, it's still extremely limited today relative to what human intelligence is.

Instead of five hundred thousand average algebra teachers, we need one good algebra teacher. We need that teacher to create software, videotape themselves, answer questions, let your computer or the iPad teach algebra... The hallmark of any good technology is that it destroys jobs.

Going out and being nice to the world at large doesn't make me feel good, so I replace that with things, with technology that does get me excited and does get my brain spinning, until one day it stops spinning, and then you can bury me.

The Internet is a limitless library at your fingertips. It's a great place to start with the acquisition of knowledge. My process is to go to a place when I'm writing about it. Nothing captures the essence, feeling and flavor of a place better than when I'm actually there and doing the writing.

I love being an enigma. Every time I'm tempted to respond to someone who tries to put me in a box, politically - you know, someone who gets on the Internet and says, you're pro-gun, or you're anti-gun - I stop and say to myself, 'This is great; this is what I wanted. I wanted to be the guy you can't figure out.'
