I have never understood completely how you would fix the problems, but
to the limited extent I do, they involve vast numbers of people
(nations) doing things you personally think would work in a

possibility. Laser propulsion isn't likely either but at least it is
something one country or even a private organization could do. That's
a different order of probability.

Well, yes. If we don't solve the energy problem well before 2050,
chances are most of the race will die of starvation or resource wars
by then. (Assuming of course that people have not mostly uploaded

more likely to work.
