It's possible that the oligopolists could become scary, rather than irritating and mildly risky. Dyson gave me a shudder with this:
"The genius — sometimes deliberate, sometimes accidental — of the enterprises is that they have emerged as something else. Their models are no longer models... No one is at the controls... The successful social network is no longer a model of the social graph, it is the social graph. This is why it is a winner-take-all game."
