However, I now drop that quibble and consider mt's question.
As usual with mt's stuff about politics, whilst I find it interesting and stimulating I also find it almost completely wrong. One piece of wrongness, although not the most important, is Ah but come back those twenty years later, and who has made progress? The scientific landscape is utterly altered, while the political landscape is the same mess. It is certainly true that not all political problems have been solved, but then the same is true of science. But politics progresses: the percentage of those living under democracy has increased in the last 20 years, and is part of a long upwards curve. Extreme poverty is decreasing. General acceptance that all people have equal fundamental "rights" spreads. And so on.
But the main wrongness, to me, is the familiar one: the desire to have govt do stuff for you. If you look at science and at politics, and despair for the progress of pols compared to science, then one reaction is to try to import some science-y-ness into pols; but another is to have govt do less. It hasn't done a very good job (the decrease in poverty, for example, is due mostly to trade / globalisation / captialism, not govt) so the best thing is to have less of it. Sadly, one of the failures of politics since the 1980's is to appreciate the likes of Thatcher and Hayek.
Related to that is Our present problems seem rooted in a lack of ecumenism, a stupid failure to see the commonality of our collective fate... It’s one world. It thrives or fails as one. This is also not really true, and the sort of thinking that leads to top-down failed stuff like Kyoto. Trying to co-ordinate a world that thrives or fails as one is too difficult; problems can only be solved by being broken down into smaller pieces. Thinking of the world is great, as an abstract concept, of course.
