AI is trained on a various range of code quality, including very low one.

I'm paid to provide good quality code and not flood my company with more average code than it should.

In my previous job, I could regularly reduce a PR code down to 10-20%% of its size because someone overlooked something or was just "overengineer" a feature.

AI are such "bullshiters" that they produce more text than necessary.

Code bloat was already real, but from my personal experience it becomes realer with AI. The outcome of this will likely be apparent when no one can dive into any code base because of the amount of fluff in it (and you will obviously need more AI to deal with this).
