I personally fear the sort of stagnation that seems to be taking place these days. Sometimes it seems like the great leaps forward of our recent past have been replaced by the tiniest of cautious baby steps moderated and all but drowned out by the clamouring of the ignorant. I fear for a world where the accountant is king, aided and abetted by craven hand-wringing risk assessors, and there's no place for a Brunel, or Concorde... or for men standing on the Moon looking back at this tiny blue pearl and reminding us that all our eggs are in this basket.
Agreed. Although, one interesting thing about the rise of the ultra-rich and the multinational corporation is that we have a sort of second tier of entities with the potential capability to get deep into space exploration. And a certain number of these people are arch-technocrats. While I don't tend to agree with some of their politics, I can't really turn up my nose at the idea of a Mars colonization mission or a space elevator, corporate or otherwise.
Sooner or later, the more malign aspects of corporate control will be recognized (re-recognized?), but, even so, private initiative may yet get us out of the bottom of this gravity well.
Failing that, there's always the proud, ambitious, resource-hungry, overpopulated, environmental-degradation-conscious-because-gee-it's-right-next-door Chinese. Assuming they don't decide to celebrate their ascendant power with a war, instead, that is.
I grimace every time I hear about more power accruing to the Chinese military-- or about its increasingly aggressive, confrontational, nationalist culture, which it seems to be encouraging in the general population, as well.
