There's a subtle but big difference between what he said (at least how I read it) and what you said he said.
You're implying he said credentials are worthless or meaningless.
He actually was saying that there's a bubble in education. That is, the cost of education is overvalued vs the return one typically gets. Yes, he talks about the exclusionary nature of institutions but I don't think his point is that credentialing is pointless. His point is that the system has built a bubble (overvalued not worthless)
