the techniques described sound like just as much work, if not more, than just writing the code. the claimed output isn't even that great, it's comparable to the speed you would expect a skilled engineer to move at in a startup environment
That's very fair, and I believe that's true for you and for many experienced software developers who are more productive than the average developer. For me, AI-assisted coding is a significant net win.
The as-of-yet unanswered question is: Is this the same? Or will non-LLM-using engineers be left behind?
