Oh and I remember the day we first got mosaic and I thought “why would I need pictures on the internet?”

Since we seem to be getting pedantic...

There's "The (capital I) Internet" - which, most date to the flag day, and the "Public Internet" (the Internet after policies changed and allowed commercial & public use over the NSFnet backbone - in 1992f, as I recall).

Then there's the more general notion of "internetworking" - of which there was a considerable amount of experimental work going on, in parallel with TCP/IP.  And of (small i) "internets" - essentially any Catenet style network-of-networks.

As long as we’re being pedantic, January 1, 1983 is considered the official birthday of the Internet, when TCP/IP first let different kinds of computers on different networks talk to each other.

It’s 2021, hence the Internet is less than, not more than, 40 years old.  Given your mathematical skills, I put no stock in your claim that we still can’t “buy an NMS that just works.” :)

Pedantically, IP is 40 years old as of last month. What you're talking about is the flag day. People including myself were looking into internet protocols well before the flag day.



In theory, there is no difference between theory and practice.

In practice, there is.  .... Yogi Berra

Theory is when you know everything but nothing works.

Practice is when everything works but no one knows why.

In our lab, theory and practice are combined:

nothing works and no one knows why.  ... unknown
