The way I think of the universe is: we are the universe discovering itself, gaining consciousness and trying to figure itself out. Our fears are exactly the same as the universe’s. Our curiosity and wonder, also the universe’s. RN, this universe is a child, maybe a baby, and the way it’s expanding, it’s processes and consciousness will simply be on a much different time/space scale, require less energy (cold dark universe) with better understanding of space time, meaning rn it’s already able to appreciate all of time forever and understands that the point is not to go back and change things but to appreciate all presents. So us humans, we will learn at our pace, and if we go extinct, we’ve played our part, maybe another species someplace else will be better suited to carry on our torch or a completely new and different kind of torch.
