AI exerts pressure to flatten roles; everybody feels the false confidence to do everything, so companies need to ensure expert oversight, and that shipping means assuming responsibility. If the latter can't be realistically accomplished, shipping should not be allowed. I think a healthy approach is to encourage everybody to create their own POCs with the understanding that only domain experts ship production code.

I still believe in ensuring that contributors understand every line of shipped code. This creates a natural ceiling on the width of their domain; though AI can help them learn more quickly, everyone can't know everything about engineering.

AI does not increase co-ordination costs per se; it increases productivity. You can achieve the same result with fewer people using AI, so it should decrease co-ordination costs. Only when you add AI while keeping the organization constant should co-ordination costs increase.
