That is patently false in the real world we live in currently. I constantly see lazy coworkers post 2000 line PRs for a trivial change that their LLM generated when 500 lines might accomplish the same in a better way. It's almost always a lazy human accepting what Claude did by default without any manual review or asking the LLM to do anything differently.

Claude absolutely loves to reimplement the wheel locally instead of just calling a method in a library we already depend on. Every doc comment and README.md update is bloated by 2-5x what's needed to communicate intent or to actually be read by a human later. It makes random drive-by edits that aren't necessary and weren't asked for in the prompt. It's a well oiled machine for producing astronomical bloat by default if you don't supervise and rein it in!
