Lynne Kiesling tilts against the neo-Luddites. It is a fine post, though I must admit that I am suspicious of that much intellectual zest that early in the morning (Matt is a patient man, clearly).
She is welcome to subscribe to my view that both Sunstein and Lessig are part of a Neo-Rousseauian conspiracy. I have no evidence of this, of course, but both of them have stylish eyewear and have probably read Emile some time during their lives.
