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.

The first half of the 20th century belongs to Picasso, and the second half is about photography. They said digital would kill photography because everyone can do it, but they said that about the box brownie in 1885 when it came out. It makes photography interesting because everyone thinks they can take a picture.

The Internet is where you can find people who are authentic.
