> So we are probably just one of the first.

We don't really have any way to know that. Considering that there may be as many stars in the sky as grains of sand on Earth, there are many many unknowns.

For another example we don't know for sure if our universe is the only one and it's entirely possible that everything that could ever happen plays out in real time across and infinite number of universes. We don't have any way to physically measure that possibility yet. We only have mathematical theories.

Similar to how Copernicus proposed the heliocentric model, maybe our universe is not even the center of existence?

It is humbling to imagine.

Astrophysicists tell us that star formation will continue for 100 trillion years.

We are indeed among the first simply because of the sheer amount of time left ahead of us vs. behind us. It's basic math. We are at 0.014% of the expected duration of this universe.

All those stars you see in the night sky? That’s an astronomical waste of energy. No technological energy limited civilization would let that waste continue, entirely unhindered.

The fact that we don’t see the light of stars, or whole galaxies replaced by dim infrared waste heat emissions means either (1) new physics will point to free energy solutions that circumvent thermodynamic laws [unlikely], or (2) we are the first.

or 3) the assumption that advanced civilizations consume more energy is wrong.

Or just maybe civilizations advanced enough for Kardyshev level 2 engineering feel no need for exponential expansion. Fermi paradox is essentially Malthusianism extended to outer space.
