One Good Reason Why Disruption of Any Media or Communications Business Still is Possible

Incomplete knowledge makes rational decision making quite difficult. In fact, some would say incomplete knowledge means it is not possible for people to behave completely rationally, even when they want to do so. 

But since it is a statement of fact that nobody can know everything, there always is the possibility that somebody, with a particular set of domain knowledge, can "see" something other practitioners--with different domain knowledge--cannot perceive. 

For that reason, disruption of any market in media or communications remains possible.
