I'm substantially concerned about the policy directions of the space agency. We have a situation in the U.S. where the White House and Congress are at odds over what the future direction should be. They're sort of playing a game and NASA is the shuttlecock that they're hitting back and forth.

I would like to see a future where artists think that they have a right to contemplate things like global warming.

Something I've realized lately, to my shock, is that I am an optimist, in that I think humans are almost infinitely capable of self-change and self-modification, and that we really can build the future that we want if we're smart about it.

I've noticed a terrible thing, which is I will agree to anything if it's far enough in the future.

You cannot fight against the future. Time is on our side.
