To be honest, I think banning "AI-pioneered" (i.e. code fully written by AI without a single human thought involved) code is still a valid idea since 99% of the time it's solving a non-existent or very edge case-ish issue by adding extra bloat code to the codebase, but what I'm against is banning experienced engineers with good understanding over code from using AI just like any other tool you have to be more productive
