I imagine they are still good hires - however there is a real cognitive debt that happens when we code with LLMs in my experience.

It’s harder to internalise concepts because you don’t go through the struggle of understanding them and finding the mental links you need to remember later.

I notice this with people around me - all of them are doing more things, but I am also catching more issues when reviewing docs and code.

Obviously YMMV.

My guess is they would take longer to ramp up but then have a better understanding of the codebase and domain.

But there’s a lot of pressure to get up to speed as a new hire and it’s easy to move fast with AI
