A lot of us don't want to be quite that serious about world problems. Our life is there to enjoy, not to be an eternal dissident, eternally unhappy with how things are and with the state of mankind.
As far as the mechanics go, working with other people on received ideas was for me a very interesting technical problem. I can't say that any of my collaborations engaged my heart, but they engaged the craftsman in me.
I like to think that I have no single view nor any single situation that I think things arrive from. I try to give examples of what I think are interesting questions for me.
I was never able to write seriously about heroes because I was very aware that I was not one and that in my background there was not this heroic thing.
I'm not so interested any more in how a great deal of science fiction goes. It goes into things like Star Wars and Star Trek which all go excellent in their own way.
It takes me a long time to get with a landscape. It took me 20 years before I wrote anything about Ibiza, and I haven't written about Oregon yet, although I've been there 20 years - possibly I'm almost due.
So I wrote what I hoped would be science fiction, I was not at all sure if what I wrote would be acceptable even. But I don't say that I consciously wrote with humour. Humour is a part of you that comes out.
