Your product managers most likely are not reading your code. Your CEO is not. The vast majority of your company is unlikely to ever look at a line of code.

If the process becomes reliable enough, then there is no reason. For now, that still requires developers to pay attention for important projects, but there are also a lot of AI written tools I rely on day to day that I don't, because the opportunity cost of spending time reading them is lower than the cost of accepting the risk that they do something wrong.

There are also a whole lot of tools I do read thoroughly, because the risk profile is different.

But that category is getting smaller day by day, not just with model improvements, but with improved harnesses.
