In the early days of the universe, before the stars and galaxies burned out, there was ample free energy. You could create an entropy gradient and extract useful work from it just by putting a heat engine in the shadow of a reflective surface. It was a wonderful time to be alive.
In the modern era, where we survive on reversible computation driven by quantum fluctuations in space-time, we refer to the youth of the universe as the "ergocene": The era of work.
The simulation you are experiencing is the best approximation we have been able to create to what it must have been like to live in these heady times.
