I picture the peak when the moons of Jupiter are full with a thriving civilization. One trillion strong under one government. Building the ships that take humanity to other stars.

How small we will look to them.

Seems awfully convenient that the universe would look identical to us in particular, as opposed to any other observer. Or being computronium.
