Yes, this matches my experience with codebases before AI was a thing.
Yes, but given a feature that should take say 100 lines of code, the average programmer will write in the order of 100 to 500 lines. If they're a heavy OOP user, maybe they'll write 10 classes that total 2000 lines. Regardless, worst case, it will be within ~2 orders of magnitude of a reasonable solution.
It's not that they're not trying to write the biggest clusterfuck possible and maximize suffering in the world, it's just that there's a human limit on how much garbage they can type out in their allocated time.
This is where AI revolutionizes things. You want 25,000 lines of React? On the backend? And a custom useEffect-backed database? Certainly!
