Does Jill Lepore's Ph. D. qualify her to talk about business?

Reacting to Jill Lepore's critique of American business's "gospel of disruption" comes this striking thought from Marc Andreessen:


The startup-news end of the tech press seems in a state of perpetual orgasm over the Netscape founder's willingness to opine on practically anything. I can't help but wonder if Andreessen mocking Lepore's credentials is key to understanding his desperation to be seen as a public intellectual—and others' thin-smiled willingness to treat him as one.
