"Accept death, it's beautiful" is cope. It's not beautiful. It's suboptimal horror.
I find it offensive that so many "universe experiencing itself" entities willingly accept a return to dust. Our sun dies, and with it everything on this planet will become metal inclusions in a decaying solar body. You know what doesn't matter in light of that? All other perspectives. Every other conception of death and meaning tends to zero.
I accept death personally. It's 99.9999manynines likely. But I would love to spend my limited energy trying to conquer it or to push forward the societal envelope. Something from earth should conquer the vastness of spacetime and physics.
It's not like how any of us spends our time matters anyway. We're all already dead, geologically timespan speaking.
And who knows. Maybe the gods of the future will reverse simulate the light cone down to your femtosecond neurotransmitter flux. Maybe that's you right now. And maybe they'll pull you forward into an eternity of bliss instead of a read-only memory or sadistic eternal hell simulation. But probably none of those things given how more likely we are to accept doom.
I hear this claim often, but I never hear any particular reason for why it's so important compared to e.g. letting Alpha Centauri colonize where the lightcones overlap.
