It sounds like part of the thing here is “you can spend energy/time/effort re-arranging matter into configurations that will survive longer, but you’ll pay a bunch of costs trying to optimize for that, and it’s not obvious that those costs are worth it.”
(i.e. maybe you can arrange a galaxy to survive as long as possible to output “goodbye, world” with minimum viable sentience at the longest possible timeslot, but, like, do you really wanna sacrifice a bajillion possible flourishing lives so that you can print “goodbye, world” at seventy bajillion trillion years instead of 1 bajillion trillion years?”)

And, well, that’s fair I guess.
