I've talked to a lot of artists - painters, writers, musicians - many of whom have had great ideas on trains. The only explanation I have is all that stuff is coming at you while you're relaxed, so somehow it kicks you into hyperspace in terms of brain function.

I'm often guilty of overcooking and too much arrangement and throwing too much at it. But I think as I get older, I'm learning better when to be empty and when to be full.

Snowden's revelations shocked the world and made it very clear why we need to have some way to look over those who look over us. With increasing terrorist attacks, security is critical, but not without any accountability or oversight.

I think another thing is that we don't really want exclusivity. We accept that it is in the artist's interest to be on sale in every place where they sell music.

Over the next decade, there will be disruption as significant as the Internet was for publishing, where blockchain is going to disrupt dozens of industries, one being capital markets and Wall Street.

My own theory is that we are in the middle of a dramatic and broad technological and economic shift in which software companies are poised to take over large swathes of the economy.

Here, in low earth orbit, we're going around the earth, so we can actually use an Internet protocol phone because we have the appropriate satellites that can get those bandwidths.

I have a lot of plants and fish and a pet lizard and Venus flytraps. I have a whole ecosystem in my room, like a running waterfall and different lights and sensors set on digital timers.
