Added some elaboration to the parent comment. I just feel that using a simplicity-based prior might solve many problems that seem otherwise mysterious. 1) I'm not a Boltzmann brain because locating a Boltzmann brain takes much more bits than deriving my brain from the laws of physics. 2) A mind running under homomorphic encryption is conscious, and its measure depends inverse exponentially on the size of the decryption key. 3) Multiple or larger computers running the same program contain more consciousness than one small computer, because they take fewer bits to locate. 4) The early universe had low entropy because it had a short description. And so on.
