Not entirely, no. I think the first point to make about the Culture is, I'm just making it up as I go along. It doesn't exist and I don't delude myself that it does. It's just my take on it. I'm not convinced that humanity is capable of becoming the Culture because I think people in the Culture are just too nice – altering their genetic inheritance to make themselves relatively sane and rational and not the genocidal, murdering bastards that we seem to be half the time.

But I don't think you have to have a society like the Culture in order for people to live. The Culture is a self-consciously stable and long-lived society that wants to go on living for thousands of years. Lots of other civilizations within the same universe hit the Culture's technological level and even the actuality of the Culture's utopia, but it doesn't last very long – that's the difference.

The point is, humanity can find its own salvation. It doesn't necessarily have to rely on machines. It'll be a bit sad if we did, if it's our only real form of progress. Nevertheless, unless there's some form of catastrophe, we are going to use machines whether we like it or not. This sort of stuff has been going on for decades and mainstream society is beginning to catch up to the implications of artificial intelligence.

Excession is particularly popular because of its copious detail concerning the Ships and Minds of the Culture, its great AIs: their outrageous names, their dangerous senses of humour. Is this what gods would actually be like?

If we're lucky.
