The minimum amount of energy needed to compute decreased asymptotically to 0 as the temperature of space goes to 0. This is the reason a common sci-fi trope where advanced civilizations hibernate for extremely long times so that they can do more computation with available energy.

That’s a common trope? Can’t say I’ve run into it. But I’d like to! What are some good examples?

In the book Calculating God, a character notes that this is a common civilization-wide choice. Living in virtual reality, rather than trying to expand into the vast expanses of space, is a common trope as much as it's a logical choice. It neatly explains the Fermi Paradox. In some fiction, like The Matrix, the choice might be forced due to cultural shifts, but the outcome is the same. A relatively sterile low-energy state civilization doing pure processing.

I wonder if it's illogical to think that all civilizations must always pick the most logical of the options

[Supermancho]

Logical and optimum are not the same.

[yetihehe]

Those civilisations that make too much illogical choices probably die off.

[ithkuil]

True. But it's not a binary choice. All it takes is to make one sub-optmial choice for the universe to be filled up with von-neuman probes in all star systems
