It's even better/worse, since we're operating on multiple worlds quantum mechanics, and many of those random events happens after the AI has stopped having an influence... If you have the AI output a bit, and then XOR it with a random bit, what bit the AI outputs has literally zero impact no matter how you count: you end up with one universe in which 1 was outputed and one in wich 0 was outputed.

... I guess this is based on the assumption that there's no difference between "universe A sees 1 and universe B sees 0" and "universe A sees 0 and universe B sees 1"... but blobs of amplitude having indexical identities like that seems like an incredibly silly notion to me.
