So basically anything that doesn't look like the conventional Internet
addresses doesn't count? Maybe it's *that* kind of metric that exhibits
the 'fascination with the past' that we're accusing the new generation
of... ;-)

A variant of Occam's Razor, of course. IMO, better to recall Maslow,
"when the only tool you have is a hammer, everything looks like a nail".
Just because you can't map these new ideas into Internet concepts
doesn't mean they're not useful, or that they're 'complexities' as per

The concepts of the Internet can be abstracted, even if they originated
as an engineering example.

Some of us have been here, working in abstractions for a long time,
having a hard time explaining it in terms of the old Internet just to
make it accessible and convincing.
