this seems like a lot of pseudo-intellectual babble that boils down to the fundamental tension between nihilism and existentialism.

I subscribe to absurdism, but after I de-converted from faith in my late teens and wrestled with these topics for a few years, I decided that my own meager contribution to humanity or the universe, even if it had meaning, was never going to amount to enough to stress myself out about it, and never really pondered it much again.

A lot of this post-rationalism stuff seems like a desperate attempt for outsized-egos to rationalize and justify their special-ness in a universe that couldn't give the slightest crap about them.
