@insurrealist

also, what happens to the psych arrow when the thermodynamic one reverses? do we get a timeless moment?

Replying to

and

or does it maybe happen inhomogenously and there are, briefly, coexisting zones of countervalent arrows?

and

I am probably not going at this with sufficient rigor, but that's just the author mind looking for concepts

and

so essentially they take a computation and construct it in both thermodynamic arrows

imagine having to heat computers in an entropy decreasing universe, installing "coldsinks"

A universe with a decreasing entropy budget; reminds of me of Ted Chiang's "Exhalation" lightspeedmagazine.com/fiction/exhala

re 4: if decreasing entropy is hostile but not unlivable, maybe increasers will encounter decreasers towards the reversal

and

an increaser crossing over, slowly dying in decreasing entropy, finally relinquishing its last bit

as a generic point I think its better to talk about resource use directly rather than complexity classes but yeah

hm I was already too brainfried, has little to do with complexity theory, more complex systems + reversibility

but of course you can sneak in complexity here through extra bits (see 3.2)
