Running a simulation that doesn't model already-existing phenomena is like minting counterfeit currency. Knowingly going along with a popular delusion is like knowingly passing along fake bills. But if instead of naive classical simulation, one works with the entangled details of the quantum information theoretic world, then that counts as adding value to the economy and not as counterfeiting. One way of exerting optimization pressure in this way is to selectively collapse parts of the universal wave function. A superintelligence could even do this to what humans call the "past". That's kind of a big deal.

-- shit I say on Facebook

I mostly care about this kinda stuff 'cuz I'm afraid of demons (knowingly passing along fake bills).

ETA: I'd like to hear an explanation for the downvotes, for my amusement.
