Surely, something you call architectures might evolve. So what?

Depending on what you call "architecture", may be or may be not.

Completely wrong.

Apparently, you haven't read the paper, which does not depend
on specific structure/architecture of the Internet with a
very old example of CTSS, reference to which was written in 1963,
and another old example of telephone networking, reference to
which was written in 1964.

As the paper is titled

	END-TO-END ARGUMENTS IN SYSTEM DESIGN

and its abstract begins with the following statement:

	This paper presents a design principle that helps guide
	placement of functions among the modules of a distributed
	computer system.

the argument is applicable to system design in general and,
especially, all the distributed computer systems including
preliminary and *EVOLVED* ones.

Moreover, the paper does not say anything about architecture
of networking (though the paper briefly mentions CPU architecture
of RISC).

So, while you can call something an end to end architecture and
say it can evolve, it has nothing to do with the applicability
of the principle, the end to end argument, to system designs
with or without the evolved architecture.

With the argument, it can be concluded that approaches presumed by
SEMI2015 is incomplete and incorrect.
