Nothing against that. As I mentioned, there’s utility there. I don’t think it’s bad to put these tools to use. But this idea of having “a bunch of extremely capable co-workers that you can let deal with all the problems” without understanding what they do or reviewing their output (due to whatever reason), in other words putting the effort and understanding the output, is exactly what I was talking about.
