And by coincidence the very next link I follow is this:

It’s true that stupidity and malevolence do sometimes play a role in the disruption of industries. But in the first part of this essay I’ll argue that even smart and good organizations can fail in the face of disruptive change, and that there are common underlying structural reasons why that’s the case. That’s a much scarier story. If you think the newspapers and record companies are stupid or malevolent, then you can reassure yourself that provided you’re smart and good, you don’t have anything to worry about. But if disruption can destroy even the smart and the good, then it can destroy anybody.

The stuff on local optimums and immune systems in this is really thought-provoking.
