Since the title isn't very informative, here's a tldr:

Is 90% of code going to be written by AI? I don’t know. What I do know is, that for me, on this project, the answer is already yes. [...] At the same time, for me, AI doesn’t own the code. I still review every line, shape the architecture, and carry the responsibility for how it runs in production. But the sheer volume of what I now let an agent generate would have been unthinkable even six months ago.
