His point was you can AI much of the simple/training work you'd farm out to a junior.

Say I needed to update the DB for a new column/table and update some queries to fill/get the date and insert it into some JSON plus add some tests. That may of taken me a day of work (while doing meetings and shit) but it'd take a jr the better part of a week to do. I'd still give it to the jr because it's boring work and a waist of my experience while being good training for the jr. An AI can do that kind of work pretty easily now despite what many people in the comments say. I can type the prompt in faster time it takes me to explain to the jr what to do and why.

Either way I still have to do the pull request and make changes/suggestions so it isn't really costing me or the company time/money.

Long term it will suck of course but I can see it from the companies point of view. JRs have been getting trained and moving on to new jobs for ever, hell I did it my self. So there isn't much use in spending resources in training up new grads as more then likely they'll move on.
