Two things to remember: barring a dark age, there will always be technological innovation, and the human population is at it's peak, so we're more likely to make advancements.
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.
I picture the peak when the entire universe is teeming with life, but looks empty to very simple creatures like us.
Seems awfully convenient that the universe would look identical to us in particular, as opposed to any other observer. Or being computronium.
