While agree that this must be filtered for his audience of students, I have to take issue with his tone that seems to boil down to what most of academia does: very unambitious incremental research. Sure - this schlep is needed, but I think his cadre our too biased in this direction. The system dislikes risky research, and that's a shame.
Also, a glance at his books looks exactly like the grade-grubbing BS that leads to kids becoming valedictorian and then failing to do anything of significance after. These zombie achievers miss the point of education, and I feel like this guy is only encouraging them.
