I had hired 3 junior/mid lvl devs and paid them to do nothing but study to improve their skills, it was my investment in their future, I had a big project on the horizon that I needed help with. After 6 months I let them go, the improvement was far too slow. Books that should have taken a week to get through were taking 6 weeks. Since then LLM have completely surpassed them. I think it’s reasonable to think that some day, maybe soon, LLMs will surpass me. Like everyone else, I have to the best I can while I can.

But this is an issue of worker you're hiring. I've worked with senior engineers who a) did nothing (as - really not write any thing within the sprint) b) worked on things they wanted to work on c) did ONLY things that they were assigned in the sprint (= if there were 10 tickets in the sprint and they were assigned 1 of these tickets then they would finish that ticket and not pick up anything else) d) worked only on tickets that have requirements explicitly stated step by step (open file a, change line 89 to be `checkBar` instead of `checkFoo`... - having to write this would take longer than doing the changes yourself as I was really writing in Jira ticket what I wanted the engineer to code, otherwise they would come back with "not enough spec, can't proceed"). All of these cases - senior people!

Sure - LLMs will do what they're told (to a specific value of "do" and "what they're told")
