There's already skill issues in the field even with senior people and without AI. It's why we test people to witch hunt for those imposters. Lots of talk about how one bad hire can ruin the whole team or something. Even competent developers stretching across multiple skillsets (front end, back end, ops) that they aren't experts in. And plenty of bad code and technical debt from bad off/on-shore contractors due to skill issues and communication barriers.

I'm not saying you're wrong though, but just that it won't be much different.
