I think a better metric these days is what percentage of code is not reviewed / understood by humans. That is the real bottleneck. Until we can stop looking at the code, AI barely matters - you are just trading quality for quantity.
Thats why it is so amazing for speed runs and prototypes. Here it is legitimately > 10X faster.
You need to retrain managers from seeing a prototype and thinking "yep, ship it" and over to "okay, how do we build this properly?" And I don't think that's gonna happen.
