Great research universities must insist on independence from government and on the exercise of academic freedom.
A movie star is someone people look at and go, 'I want to be like that person'. There's the responsibility of desire. It's not something I'm interested in trying. I would fail miserably at it, so why even bother?
I just want to work on things that are really hard, and when I'm not working on things that are really hard, I want to hang out with people I like to be with, and that's it.
