I read the first two paragraphs, found a bunch of fairly glaring errors, and got put off.

>It has type hints, which are optional, which means they’re not there.

I mean it is there, and it works.

I've also not had an AI make a dict key error in a while, but mostly as I use objects - haven't magic strings in code been bad for a while now?

Also llms are bad at architecture, not things like typing or keys. I'm really struggling with even opus having an absolute atrocious abstraction approach, and has made implementing business logic incredibly difficult. Borderline having to throw out days of work.
