By a "meta solution" I meant, e.g., coherent extrapolated volition, or having an AI that can detect and query ambiguities trying to learn human values from labeled data, or a Do-What-I-Mean genie that models human minds and wants, or other things that add a level of indirection and aren't "The One True Goal is X, which I shall now hardcode."
Can you say more about what you thought was meant? My reader model doesn't know what interpretation brought you to your guess.
