I think you could extend this observation even further. Business culture has a habit of sh*ting on new knowledge as being useless because businessmen often lack these knowledge yet still manage to succeed. An example of this is the general disdain for innovative approaches.

They fail to realize that the reason they're succeeding is not because traditional business know-how is useful but rather because crony capitalism allows you to succeed without innovation. However this advantage disappears once a market disrupter appears. We are currently in a golden age of innovation, but that won't last forever.
