We're working in a really deep area where having full understanding of our code is more important than speed.
Besides, in this area, clients getting one whiff of AI code would be an immediate deal-killer
If you implement AI code review suggestions then you're using AI code, just the hard way.
Also I don't see why your clients would be ok with having AI review and influence your code. Seems hypocritical, or like you're trying to cheat them.
Re "the hard way", I disagree. While it may seem like the hard way, in the medium and long term this is turning out to be the easy way. We have basically no technical debt, we can fix issues rapidly and (intangible I know) we can stand behind our codebase with absolute confidence.
