Replying to

and

it explicitly doesn't say that psych. and thermodyn. arrow can be opposed, it would be an interesting implication though

Replying to

and

consider two civilizations living in different arrows, either completely ignoring each other, or trading

Replying to

and

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?

Replying to

and

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

Replying to

and

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

Replying to

and

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

Replying to

and

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

Replying to

and

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

Replying to

and

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

Replying to

and

hm I wonder if you could construct a decreaser? from our view, it'd look normal, it'd just think backwards
