One reason for my curiosity is that the author isn't claiming humans can do any of those things you talk about automated tools doing better than the automated tooling does. They're talking about it as a learning opportunity to see how other parts of the codebase work, and as an exercise in communication and teaching, all of which I can see the value in. In other words, your claims and the concerns backing them seem to be orthogonal to what the author has actually written.
What do you think about that?
