someone probably made this same argument against certain frameworks over the years and juniors still figured it out. we need to stop trying to babysit learning for hypothetical situations.

the bar to "start" is lower and the bar to actually competency is higher now, juniors who want to actually learn instead of just pressing enter over and over again will do so regardless of whatever you do to "help" them.

It's not really a hypothetical. I work with one junior who's submitted an incorrect bugfix 3 times and counting; he seems genuinely incapable of processing the idea that there's a correctness issue he has to resolve, rather than a prompt engineering issue that will allow Claude to figure it out if only he asks in the right way.
