He is. When he started, a CPU with 8mb of RAM was a marvel and as
big as the average office desk (IBM 1130 - 1970). He is only as
meaningful as I need him to be.

We'd be fighting over definitions again and I am not a technologist.
Can you prove in the concrete that a better system can't be built?
If you can, then see my last statement: the mission is over.
The Internet is still the Internet despite all the applications
sitting on top of TCP/IP. OSI might have been better; it was a better
architecture or so it was claimed, but it wasn't free and once the
WWW landslide built over free software and liberated DoD technology
was underway, no arguments to the contrary were being entertained
as long as that bubble of users and investment was expanding.
As of last week, the number of .com name registration renewals
began to decline. Amazon.com made a profit of 1 cent a share.
AOL is bidding for Red Hat but why does a media company need a
software services company? Everyone is rethinking things in
the face of competitive pressures. That is the world before
and after the web bubble. Get used to it. We are too much like
a group of circa 1969 fifteen year old kids believing the revolution is
won and no one has to prove anything again.
What is happening today is that people are looking at the basics
of Internet systems and inquiring where possible improvements can
be made. Two raised here are HTTP ubiquity vs other protocols,
and the use of flags of some kind to indicate the semantics suggested
for processing an XML instance.

Logic implemented in an executable or interpretatble script.
HTTP is a convenient layer over DNS. I was navigating with
telnet before a web browser was a gleam in DARPA's eye. It
wasn't as easy and it definitely wasn't well coordinated or
as fixed on a single display system.

A "system like the web". What is the web?

I apologize. I thought you were the one emphasizing URIness as the
unique characteristic of webness. What is the web? If we say it
is HTML and URIs, we leave out a lot of technology and technologists.
Even if we toss in XML, we leave out non-URI-based XML applications.
If we assume URIs are of necessity core to XML, we leave out a lot
of interesting applications. Are we choosing a technology so some
people's jobs can be simple, or simplifying a history so it will be believed?
Parts and assemblies: it's in the way that you use it.
