I recently pair-worked with two junior developers (on their first job, but still with like 2+ years with the company) in order to transfer the know-how of something.

I realized that they are shockingly bad at most basic things. Still their PR:s look really good (on the surface). I assume they use AI to write most of the code.

What they do excel in is a) cultural fit for the company and b) providing long-term context to the AIs for what needs to be done. They are essentially human filters between product/customers and the AI. They QA the AI models' output (to some extent).
