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.
