Using AI doesn't necessitate "vibe coding" - there are smart ways to use AI, where you are managing and structuring the process, as well "vibe coding".

I guess the problem is that AI now allows non-programmers to program. It would be a bit like giving everyone a scalpel and they now either consider themselves to be surgeons, or give it a go regardless since now they can.

I'm not sure where you are getting software engineers that are "bastardising" your ideas?! You may want to look elsewhere, or pay for someone better !
