me. I'd assume that billions and billions of years would be enough for some strategy to be formed around this heat death thing. Humans have come so far in such little time, and that's with our terribly short lifespans. If we were to attain near-immortality and a bunch of geniuses had billions of years to study I think they could probably find some sort of solution, at least to survive in some local capacity.
The other result, where the universe contracts and explodes again, is something I'd find far harder to survive.
