What would be found here in a thousand years much less a million?

My attitude is that it's something similar to getting ready for the end of the world by putting money in a savings account. If the money (or gold under your bed, cans of beans in the basement or even a pistol in your nightstand) does any good then it's not the end of the world.

If the universe is so crowded or so good at finding things like voyager that it's found in a meaningful (i.e. before humanity goes extinct or joins the godhead) time frame then we would have that encounter if voyager existed or not.
