Right. Centralization is a physical fact of the Internet as we now know it.
AFAIK though, DARPA wanted a design that could survive nuclear war due to its' distributed nature. Has the Internet and in particular TCP/IP, been successful in that regard? It would appear not.
We wanted anyone to be be able to be a first-class citizen of the Net. But we ended up beholden to our Monopoly ISPs. TCP/IP only gives first-class status to ISPs, not to us. BGP doesn't scale if we all tried to have our own first-class routers.
Yes, things are getting better in all sorts of industries; a similar boom occurred with the wide-scale deployment of the 19th century Railroads. But things got better still with the deployment of automobile roads.
I propose we do the same with a globally scalable mesh network.
