So, an inherently error-prone computation is being corrected by another very error prone computation?

No problem, said von Neumann. https://www.scottaaronson.com/qclec/27.pdf

what he actually said: "as long as the physical error probability ε is small enough" you can build a reliable system from unreliable parts.

So it remains for you to show that AI.ε ~= QC.ε since JvN proved the case for a system made of similar parts, that is vacuum tubes, with the same error probability.

(p.s. thanks for the link)

A quick careless Google didn’t yield Scott Aaronson’s take on this, which as a layperson is the one take I’d regard seriously.

Has he remarked on it and my search-fu failed?
