Boltzmann brains necessarily have a low energy of computation? Relative to what? The heat surrounding them?
Don’t we also, relative to that?
Can it actually be argued that the total energy of life-supporting universes (not even limiting it to just the cognitions inside them, just the whole thing) is higher than the total energy of boltzmann brains within the much more frequent highly entropic universes? I’m not even sure of that. See, I’d expect orderly universes to be much less frequent than highly entropic universes, order requires highly intricate machines—with just the right balance of push and pull and support for variation but not too much—which so easily collapse into entropy when the parameters are even slightly off.
But I’m not sure how that ratio compares to the rate of boltzmann braining, which is also very low.
I think that most BBs have low energy in absolute terms, that is, in joules.
While total energy and measure of BBs may be very large, there are several penalties which favour real minds in anthropics:
Complexity. Real mind capable to think about anthropic is rather complex, and most BBs are much simpler, and by saying “much” I mean double exponent of the brain size.
Content. Even a complex BB has the same probability to think about any random thing as about anthropics. It gives 10-100 orders of magnitude penalty.
Energy. Human mind consumes for computations, say, 1 Watt, but a BB will consume 10-30 orders of magnitude less. Here I assume that the measure is proportional to the energy of computations.
Side note: there is a interesting novel about how universe tries to return to the normal state of highest entropy via creating some unexpected miracles on earth which stop progress. https://en.wikipedia.org/wiki/Definitely_Maybe_(novel)
Note that the part of your reply about entropy is related to a plot of fictional novel. However, the plot has some merit, and a similar idea of anthropic miracles was later explored by Bostrom in “Adam and Eve, UN++”
