I have been coding and athletic training for about as long as eachother, your anecdote works. However just like in physical training, you should really spare your energy for stuff that you enjoy and actually progresses you.

By using LLMs to do some of the stuff I have long gotten over, I have a bit more mental energy to tackle new problems I wouldn't have previously.

As well LLMs just aren't actually that competent yet, so it's not like devs are completely hands off. Since I barely do boilerplate as I work across legacy projects, there's no way Claude Code today is writing half my code.
