The space program caused so much future-thinking in culture. People who couldn't go to the Moon were building space-fantasy chairs and corsets and hairdos and anything that they could put their hands on.

The Stonehenge proposal got a lot of interesting criticism. One of the best - or worst - said something like, "Go home to Las Vegas." I think this project could possibly be realized at a very late part of my career. Right now, I don't have the authority, the budget, the credibility.

Of course I can have a simple reaction of sympathy and sorrow to destruction. But you also know that you can't have new things if you don't occasionally destroy the old. That's something you're really not allowed to say because things are often destroyed according to particular power relations so it means taking a stand in those cases, which I am not really interested in doing either. I think I am simply interested in looking.

I've made a poster at home. You know the iconic image of Che Guevara, the black and red graphic of his face? I think it's the perfect graphic, the best graphic ever made. I cut a Concorde out and put it over his head so it's Che looking up and the Concorde going by. Both are dead, maybe obsolete.

I think the optimal artwork is in constant circulation with the world around itself.

There are ends, occasionally, with projects. That happens. But they are natural dead ends. It's usually the outside situation that demands an ending. I never really settle for one.

"Hello" is pseudoscience. The only smart way to read it is not to believe in it, not to trust it, or to put yourself in it and imagine what's out there that you haven't been told or seen.
