Yes, in billions of years we'll have a problem with our expanding star, and in quintillions of years the whole universe may completely run out of fuel, or suffer a Big Crunch... Clearly we're talking about different timescales and priorities. Space exploration is reasonably a low-priority quest for now. If we manage to control our most pressing (short-term) problems for, say, a mere thousand years, technology will presumably take care of a lot of that. And a thousand years is a blip in that kind of timescale.
