Skepticism, Science & Pseudoscience

Right now, our pre tier 1 selves see that primarily in things like fighting climate change, poverty, medical advances to add a year, five years, dare I say ten years to our lives.

Eventually though, the sun's gonna get big, and survival will mean being able to move from planet to planet, not to mention the stray rock that comes along every once and awhile...so our hopefully tier 1.whatever selves will be able to muster the energy to do that, which means both space travel and terraforming.

Eventually though, stars are going to start going out, and those tier 2.whatever folks are going to want to be able to figure out how to reuse stars, refurbish, renew.

Over a long time, I'm going to need to figure out how to survive when all of the stars in the universe are dying out. My tier 3 or more self will have to figure out either how to reboot the universe or cross over or create a new universe.

It's always going to be about survival I think, just on longer and grander scales as we get further along, assuming we ever do.
