Apart from this being erroneously supralinear, you shouldn't ask people like me. I once thought there was hope for humanity, now I think we're, how you say, f***ed. Not that I'm a malthusiast, I just can't see any way we can wrest communications from the greedbags classes, get hold of physical power, and convince the minority of people who are needed to keep them in power that they are acting against their own interests., before the population hits catastrophe levels. And even then we've got to get it down to perhaps less than a billion without cruelty, coercion or discrimination.

Still, if half the punters here are right, we'll get to experience what comes next, if not as a human, as whatever evolves out of the mess, so why worry?
