I think the comparison to LLM use is a bad idea, because LLM use has pretty clear adverse effects on your capacity to program unassisted, and almost certainly long term limits your potential growth as a programmer, in ways that the LLM can't compensate (at least, not with current tech). Basically using LLMs extensively as a junior may well make you a better junior, but guarantee you'll never be a senior.

My understanding is that that GLP1 drugs don't actually have this effect, as much as we know so far.
