i do think in cosmological timescales eventually life will become impossible and later computation/simulation of life will become impossible. idk how exactly it will look like theyre changing the predictions every decade these days (big bang, big rip ....)
i think specieation is somewhat arbitrary and has some conflicting definitions. the most straightforward one is mating if two individuals can produce a viable offspring they are the same species and by that definition i do think there will always be humans that can mate with 2025 humans but they might be like 0.00001% of the population 100000 years from now
