You can yoink energy from a spinning black hole so there's ways to keep on trucking in the dark universe
I mean the period of heat death beyond that. The black holes have to be fed and eventually that matter will dry up. The universe will keep expanding and chasing thermodynamic equilibrium until some maximum point of entropy where every particle is spread out over increasingly vast distances, with such a total loss of interactions between them that temperature across the universe is 0 K. We'd be doing the Alpha Centauri generation ship thing but to find the next electron.
a scifi book where the last humans go around the universe with ftl tech powered by the use of spinning black holes, which they feed all the other black holes in the universe to, stoking the last fires of humanity, until all the remaining matter in the entire universe is within their spinning blackhole, and they have nothing left to throw in but themselves.
still nothing compared to the amount of time that would come after even that final black hole that ate every other black hole dissappeared
