Because “thinking” is an ability that implies the ability to predict future states off the world based off of previous states of the world. This is only possible because the past is lower entropy than the future and both are well below the maximum possible entropy. A Boltzman brain (on average) arises in a maximally entropic thermal bath, so “thinking” isn’t a meaningful activity a Boltzman brain can engage in.
Non Mathy answer:
Unlike the majority of LW readers, I don’t buy into the MWI or Mathematical realism, or generally any exotic theory that allows for super-low-probability events. The universe was created by a higher power, has a beginning, middle and end, and the odds of a Boltzman brain arising in that universe are basically zero.
No.
