This post seems like some decent advice mixed in with a lot of overconfidence and unverifiable claims.

“expert developers whose skills have reached the point where they outclass any and all “frontier AI models” in their area of expertise”

Are any developers saying they outclass any and all frontier models? I’d say at best it’s mixed at this point. The best developers still do certain things better, but not even close to all things.

“The problem is that even code written and/or reviewed by Fable 5, will stink”

I’m skeptical. Example prompt and output please.
