"which is actually going to be attempted"
I'm not convinced yet. Yes that is why people are talking about it instead of talking about attempting to colonize Antarctica, or the bottom of the ocean, or whatever. But they currently aren't attempting to colonize any of those places, including Mars, and we have yet to see them attempt any of them, including Mars.
Well, I suppose it depends where you draw the line.
SpaceX has built real physical components for its Interplanetary Transport System, which is specifically designed for missions to Mars. That's more than just talk.
But I suppose there was seasteading... though that actually did fully close down.
A bit about our last few months:
We care a lot about AI Safety efforts in particular, and about otherwise increasing the odds that humanity reaches the stars.
Also, we[1] believe such efforts are bottlenecked more by our collective epistemology, than by the number of people who verbally endorse or act on "AI Safety", or any other "spreadable viewpoint" disconnected from its derivation.
Our aim is therefore to find ways of improving both individual thinking skill, and the modes of thinking and social fabric that allow people to think together. And to do this among the relatively small sets of people tackling existential risk.
Existential wins and AI safety
Who we’re focusing on, why
