re: The World Without Us
"And what about the Voyager and Pioneer spacecrafts? Can we live long enough to build a spacecraft that could outlast us even after the Sun becomes a white dwarf?
Sometimes, I wonder if that's so important, anyway."
It IS important to leave something wonderful behind even if we're not around to benefit from it. Be it with friends and family and of course, space.
Even though we've labored and it's recognized now, it's also nice for it to be recognized by others in the future.
