That's grandstanding and dodging my argument, which is that you shouldn't be giving LLM-suitable tasks to juniors anyway. They should get first pass at the interesting, complex work -- first in digestible bites, then with greater scope and independence as they become less junior. Is years of practice required to achieve non-junior skill? Sure, but years of copy-pasta-ing boilerplate (or otherwise writing gruntwork code that could be generated by GPT) won't count toward that time & experience.
Give your juniors real, interesting work and keep the GPT-level tasks away from them, and they'll actually improve.

Your hiring process may vary, but mine sure says "yep, zero value in leetcode."
