When estimating, we'll prefer higher estimates that increase the odds of it guessing a password; after all, the point of this exercise is to establish an *upper* limit on password strength. We'll also simplify: for instance, the MOAC will not waste any heat, and the only way it can guess a password is through brute-forcing. Focusing on too many details would defeat the point of this thought experiment.
I won't address any particular encryption algorithms; this is just a pure and simple brute-force attack given precomputed password entropy. Furthermore, quantum computers can use Grover's algorithm for an exponential speed-up; to account for quantum computers using Grover's algorithm, calculate P(n/2, e) instead.

Others are better equipped to explain encryption/hashing/key-derivation algorithms, so I won't; this is just a pure and simple brute-force attack given precomputed password entropy, assuming that the cryptography is bulletproof.
Obviously, I'm not taking into account future mathematical advances; my crystal ball broke after I asked it if humanity would ever develop the technology to make anime real.
Finally, there's always a non-zero probability of a brute-force attack guessing a password with a given entropy. Literal "immunity" is impossible. Lowering this probability to statistical insignificance renders our password practically immune to brute-force attacks.
