That's fine and all, but if TCP/IP is no longer in play, how would a network like this even get started? The ISPs won't support it and there would be no way to connect nodes other than go to back to sending tones over phone lines or attempt some type of mesh network.
I get it if the goal is to explore ideas, but any serious proposal that starts with "get rid of TCP/IP" isn't a serious proposal because that stipulation alone makes it dead on arrival. Unless you could convince major internet backbone providers to adopt a complete replacement because of fantastically convincing reasons, dropping TCP/IP simply isn't going to happen. Case in point: we've had a pretty damn good reason to migrate from IPv4 to IPv6 for decades now and we all know how well that's going.
maybe not today or tomorrow, but having an idea floating around helps people consider it in the far future if an architectural change becomes necessary
Yeah, I agree. I wouldn't say it's impossible, but it would be a very steep uphill battle. What we have now works great and we shockingly got the rest of the world to agree on it. The current OSI model provides a lovely blank canvas for all sorts of communication. Can it be improved? What system can't? But from the days of ARPAnet to now was a long journey and this new Internet would have to start at the beginning and come into being like the Internet we all use today. I'm not interested in using dial-up again or waiting years to get "new" broadband. Too much investment is needed for such little reward.
Also, I feel like the author of this idea needs to brush up in their Internet history because it can't be called Internet v2 for the reason you said.
