If peering is untenable because it leads to outcomes like the one we have now (Netflix) where it is fundamentally unfair to one party (assuming that is the case) or the other, then we're all screwed. There might not be a fair solution that still manages to resemble the Internet.
In one alternative, the Comcasts and the AT&Ts are smited and no longer exist, and Level 3 goes into the consumer internet business, connecting things end-to-end. That's not something we could trust them with. Same if Comcast replaces Level 3.
In another, Netflix continues to pay the extortion (if it is that) which we have little doubt that Comcast will continue to ratchet up the price for. Or Comcast has to shoulder that burden alone (and can't charge customers extra for doing so, without people screaming "net neutrality!").
Or maybe services like Netflix just can't exist in such an environment. Also a bad outcome.
Or god help us, internet infrastructure is nationalized, and the same people who manage our roads and traffic lights take over.
Am I blowing this out of proportion?
