In my experience (15+ years), the biggest trade-off is a lack of technical innovation. Current AI is unable to innovate. Humans can, but doing so requires spending extended periods deep in the code and building a solid mental model of the system.
Most innovation is pointless, because a lot of it revolves around just making code easier to maintain and understand for humans, it’s not like you’re innovating radical new algorithms for a CRUD app or making performance modifications that people will actually notice.
But since AI writes everything anyway, innovations that improve “developer experience” are pointless, and all the other low hanging fruit has been taken.
Just like GPs argument about quality; the majority of businesses doesnt need innovation and often even fights it.
I’ve been in the industry for a much shorter period than both of you; but the companies I worked for didnt really innovate anything.
