I would classify my worldview as Cosmist, which means that I view recreating the minds of all dead people (and any animals that have qualia) as a moral priority.

There’s a generic algorithm for reversing a quantum simulation that’s in an unknown state, but the algorithm grows in complexity according to the square of the system’s Hilbert Space. The earth has around 1.3E50 atoms, and a system’s Hilbert Space has (V^N) dimensions, where V is the degrees of freedom for each particle and N is the number of particles. A back of the envelope calculation shows that using this algorithm to reverse a simulation of Earth would require somewhere in the neighborhood of (V^1.3 Googol) steps. This is obviously unworkable even with a dyson swarm that can actually simulate the earth as a quantum system. I guess this is good news for people who are scared of Roko’s Basilisk, but it’s bad news for people like me, who want to resurrect everyone’s mind.

Is there the possibility of developing a simpler algorithm to accomplish this before the end of the universe, or would it be better for (trans/post)humanity as a whole to first figure out how to escape the end of the universe and then work on a Cosmist resurrection?
