Humanity lacks goals, in some ways, I think. Wouldn't it be amazing if all the art we enjoy today still existed and was still understandable in, say, a billion years?
That isn't a totally unreasonable goal. No one spends much time thinking about it, but I see no reason to think it definitely couldn't be achieved.
If we don't set our sights long, all we're doing is failing to make it to the end of the century.
