You come across as someone who has never worked on a real software project. Humans create tons of bugs on a regular basis. AI is already better than most programmers.
Better at writing one piece of code, maybe.
Better at writing code within a huge system, definitely not. Maybe in the future, but as of Astra, Fable 5.1, the answer is still no.
AI is the average of all programmers.
It's just that many (I guess that includes me? :D) assumed that they are better than the actually were.
I have worked my entire life as a professional software developer and I agree, even among senior developers I would guess [way] less then 10 % consistently produce high quality code. But if I have to decided whether I want to use an AI to help me write code, I does not matter if it can write better code then an unexperienced junior, it has to write better code than I would on my own.
