I agree: I'm finding Keller to be very closed-minded in his worldview. He has "cooked-rock" thinking; his idea of computation is completely oriented around the physical design of silicon circuitry, and he's completely forgotten how surprising it even is that computation can be physically embedded. I'm going to listen to the entire interview, but this is definitely a disappointing listen.

Edit: Feeling a little ill. Asked whether he feels responsibility for the social impact of smartphones, he says that there's literally millions of folks like him working on technology like his, and that if he didn't do it, somebody else would.
