There used to exist the Steady-state model. If it was true, then the problem would immediately dissolve because classical minds would emerge with a far, far bigger density than the paradox-inducing Boltzmann ones. This could imply that the real physics (not even metaphysics!) also somehow dissolves the issue, but we have yet to understand the mechanism (a false vacuum decay which stops the universe from expanding and creates matter in sufficient quantities to make classical brains likely to emerge instead of the Boltzmann one?)
What is weird about this, is that in an eternal steady state universe the number of living observers in a given time period is much larger than the number of observers (including Boltzman brains) in a simialr slice of a universe approaching thermal equilibrium. So, depedning on how your Anthropic reasoning work, you could argue from the fact of your own existance that the universe must be steady state, regardless of any evidence otherwise.
(This is kind of a tension inherent in all Anthropic arguments, I am more likely to ‘be me’ (as opposed to someone else, like a Boltzman brain) in a universe with fewer people, but most possible observers are in the crowded universes, so I am more likely to be in a crowded one. Similar logic, threading oppsosite conclusions.)
