It looks like this was briefly touched in the article, but LLMs don't learn shit.
If I tell you your use of a list is dumb and using a set changes the code from O(n) to O(1) and cuts out 15 lines of code, you probably won't use a list next time. You might even look into using a deque or heap.
If your code was written by a LLM? You'll "fix" it this time (by telling your LLM to do it) and then you'll do it again next time.
I'm sorry, but in the latter case, not only are you mentally handicapping yourself, but you're actively making the project worse in the long term, and you've got me sending out resumes because, and I mean this in the politest way possible, but go fuck yourself for wasting my time with that review.
