Anyway: how will humanity evolve? (peace & love everywhere, or the usual wars keep happening forever). Will humans ever achieve interstellar travel? Will our far-future descendants be machines/robots/something else? Will we manage to fabricate biological life from dead/raw materials? (personal guess: yes). Will we encounter aliens? (or perhaps more likely: artefacts left by aliens). Will science manage to find a "theory of everything"? How will Earth be doing 1000, 10k or 100k+ years from now?

All in all: the big science / humanity / life / nature-of-our-universe questions.
