He is good at finding information and trying to present it, but, I would take all of his opinions with a grain of salt. He would go up to Jim Keller and try to teach Keller how to "properly" design a CPU if he had the chance. As far as I can tell. He would tell an ARM architect that he understands the product that architecture help design better than the architect.
A large grain of salt.
