Off-topic nitpick: I believe this sentence is untrue: "And Intel had to invent a whole new kind of transistor since the ordinary kind doesn’t work at 22nm scale." First, regular transistors do work at the 22nm scale (but tri-gate/finfet transistors work better, if you can pattern them reliably). Also, Intel didn't invent the tri-gate/finfet transistor. They just got it to production first.
To be fair, he said he's not a hardware guy. But he also is right, FinFet transistors are better for power consumption and that's really important in mobile devices
