Great insights. Inline.

You do know it actually is not an elephant, right ?

I think there are a lot who could think beyond that past defined box.

Just because billions of people drive cars without understnding how they
work doesn't mean you do not need people to think about the future of
how cars could/should work. Even beyond electric engines.
But i get the point that user/application interest would completely
outweigh any lower-layer discussions. I would consider any such
discussion a success and worst case one might need to carve out more
mailing lists to keep specific groups interests focussed.
Right now i would not be worried about that.

Yes. Or from distributed to centralized or at best little decentralized
due to hierarchical "SDN" style orchestration.

The non-radio side of 5G is just a distributed overlay application. It
does today AFAIK not cover the actual management of physical underlay
resources. Thats one of the big contention points going for who will
design that. The way i see it, 5G/6G underlays that do have good
loss/latency/throughput management could easier be built with IEEE
technologies than IETF technologies. Unless we would start to think how
to move beyond our current understanding of how to build the Internet.

Yes, very nice overview. I probably agree with a lot ow what you wrote
there, but haven't thought hard about all of them.
IMHO, the Internet will evolve into Fronthaul connecting devices&users
to edge-DC and backhaul interconnecting edge-DC. That evolution takes
out most or all problematic transit issues from the frontaul, therefore
enabling a lot more interesting network services than just best-effot
much more general than those are today. Will it be possible/desirable to
build new business around it. Thats the better question.
