I imagine the same thing happened when journalism was revealed to be yellow journalism, and other technologies slowly reveal their effect through generational adaptation.
In one sense, it's the same thing that happens because of the cycles of birth and death; technologies and cultures are born, and they are subject to death too. It's not surprising, but it is surprising, because the stuff that changes is not always the stuff you expect to change. In another sense, it's screwed up, and the only thing I can really hope for is that some kind of overarching balance can be intelligently directed towards and balance can be achieved. The idea that this is actually progress, and not just yet another side of the same coin that will eventually flip again.
