Why do you think space exploration matters? Self-sustaining space colonization is decades away, and wouldn't help against UFAI. OTOH, it might help in the case of global war, if there are some colonies that all sides are nice enough not to attack.
I can't think of any risks that space colonization helps against that deep underground colonies wouldn't, though space colonization has the huge advantage of being much more popular.
(Also, asteroid mining is a WMD and might increase x-risk for that reason. On the other hand, cheaper more abundant minerals might be geopolitically stabilizing — or destabilizing, for all I know.)
Other existential risks that are impacted by space colonization include asteroids and sudden diseases. One other thing to keep in mind is that if the Great Filter is some specific advanced technology that we haven't yet constructed, then it is likely that space colonization will allow some avoidance of that. This follows since any such technology will likely not be able to spread much beyond the planet where it occurs (otherwise we would have started to see signs of its spread in the star systems that are the graves of civilizations). Thus for example, the...
Don't let your minds be killed, but I was wondering if there were any existential risk angles to the coming American election (if there isn't, then I'll simply retreat to raw, enjoyable and empty tribalism).
I can see three (quite tenuous) angles:
But these all seem weak factors. So, less wronger, let me know: are the things I should care about in the election, or can I just lie back and enjoy it as a piece of interesting theatre?
