Doesn't using an #LLM to create large portions of your codebase mean that you end up with a lot of code that nobody understands unless they put in the time to go through it and learn what it's doing? If so, it's not much different from writing the code from scratch in the long one. :/
(Yes, I know about boilerplate and do think that's a valid use case as long as you know what the boilerplate is doing.)
