It isn't 10% less quality. It is more like 90% less quality. It does great at basic coding, but still royally sucks at system design. It codes itself into corners that need to be completely refactored. It picks the first path it sees that works, even if there are better solutions, because it doesn't understand what is available as built-in features of different tech stacks and platform. Or, to be more accurate, it doesn't understanding a single thing it is saying, so has zero thought to put into what is actually the correct solution. My favorite one is when it delivered a DB schema to me that re-invented auto-incrementing fields by creating new stored procedures and triggers... for IDs that weren't even auto-incremented.

So I feel just fine. I use AI when it helps, I do the work myself when it doesn't. All you need to do is learn which is which.
