I think this code is at least twice the size than it needs to be compared to nicer, manually produced Python code: a lot of it is really superfluous.

People have different definitions of "reasonably maintainable", but if code has extra stuff that provides no value, it always perplexes the reader (what is the point of this? what am I missing?), and increases cognitive load significantly.

But if AI coding tools were advertised as "get 10x the output of your least capable teammate", would they really go anywhere?

I love doing code reviews as an opportunity to teach people. Doing this one would suck.
