If you care for music that touches on climate change and class disparity, you could check out King Gizzard and The Lizard Wizard’s albums Infest The Rats Nest and PetroDragonic Apocalypse; or, Dawn of Eternal Night: An Annihilation of Planet Earth and the Beginning of Merciless Damnation.
I really enjoy those albums even though I don’t typically get into Metal music.
For something that’s not Metal, the song Plastic Boogie from their album Fishing For Fishies is also great.
Doesn’t this kind of assume humans are a central focus of the simulation? What if the universe is a simulation, but the rise of humans was an unintended result in the simulation. Maybe there is actually other civilizations elsewhere that are the actual focus, or just to get a look at the diversity of life that would form throughout the universe. Or, maybe life in the universe isn’t the focus at all and they just wanted to look at the evolution of galaxies and the like.
Or maybe I am misunderstanding your point. I kind of like the idea of being an unintended result of a simulation meant for other things though.
