I experience a productivity boost, and I believe it’s because I prevent LLMs from making design choices or handling creative tasks. They’re best used as a "code monkey", fill in function bodies once I’ve defined them. I design the data structures, functions, and classes myself. LLMs also help with learning new libraries by providing examples, and they can even write unit tests that I manually check. Importantly, no code I haven’t read and accepted ever gets committed.

Then I see people doing things like "write an app for ....", run, hey it works! WTF?
