> to become good at the thing in the first place requires a complete reversal of the mindset that would lead one to having wanted to hand it off
Is this true? I can be good at something and be happy to not have to do it anymore I feel
Though not the other way around. You don't become good at something by handing it off. In that case you either are already good, or never become good.
My opinion is that juniors need time in the saddle to develop good engineering judgement and taste.
Outsourcing critical thinking is seductive and a slippery slope. LLM lures juniors into feeling productive, and molds them into ineffectual middle managers to be readily replaced when there's a bad quarter.
