I disagree that it contains a kernel of truth, though I would agree that it truthfully identifies a malign surface growth that occasionally metastizes and, left unchecked, destroys the kernel. I certainly agree that there are people who teach because they can't do, but I don't think that teaching because you can't do is even part of the kernel of teaching. As for admins... this is a huge problem right now. They are threatening to destroy the host. But a healthy host does have a trim, effective, and dedicated group of admins.
