I said I had zero concern for the quality of the code. That is, I do not have concern that the quality of the code will be a concern in and of itself.

It's a subtle, but IMO important difference. We only care about code quality so as it gives us stable, understandable systems. Historically that meant a human had to read and understand it. Suppose a future where that's no longer the case, then we may still end up with stable, understandable systems without understanding every minutiae of the substrate. It's the same way I don't really know if my compiler is correct, but the behavioral patterns of my code suggest it is without me understanding anything about its code quality.
