That was only the beginning of the piece and really serves no purpose that I can see except for setting us up with some images of failed companies, which isn't something anyone in the US has any need to imagine these days.
I don't think credentials qualify her, or anyone else for that matter, to opine on anything frankly. Credentials have a lot less to do with intelligence, insight and effectiveness than do emotional honesty, temperament and open-mindedness. Ms Lepore seems to display those qualities pretty well. She doesn't bash anyone, she just lays out the facts that Christensen's theory of disruption, and the hacks running with that particular banner, are maneuvering on very shaky foundations. Their over-confidence in their theory blinds them to the complexity of reality, which she exposes very well.
And do we really need to hear anything more from Andreesen, the man who keeps reminding us that smartphones give us superpowers? His response is also ironic in that Andreesen's career is testimony to one of Lepore's points that "disruptors" can quite easily be destroyed by incumbents who may move into a new innovation late, but then quickly dominate it, to wit: Internet Explorer in 1999 or thereabouts.
