Happy to be called an idiot by the likes of yourself! Means I'm doing something right.
You missed more than a decade there. The first idea for the ARPANet came from Robert Taylor, head of the
Information Processing Techniques Office (IPTO) at the Advanced Research Projects Agency, in 1967. Funded by the evil, socialist, marxist, woke government. His realization occurred when he had to use three separate, independent terminals to manage three computer projects at three facilities. Couldn't they all be integrated onto the same network?
The first ARPANet connection happened between Stanford and UCLA in 1969, utilizing computer science experts at both schools. Or as you call them, two tyrannical, dictatorial, centralizing Hitlerian and Marxist Fascist academic bureaucracies. To use your language, they wasted your taxpayer dollars to do a stunt that had no commercial value whatsoever.
Then in 1973 Vint Cerf at Stanford and Bob Kahn at DARPA (again, two evil, socialist, tax-dollar-wasting organizations) created the TCP/IP layers of what is the modern Internet. The documentation of these protocols also contained the first mention of the word "Internet."
Next in 1974 Yogen Dalal proposed what is now the modern network interface stack, explicitly separating TCP and IP protocols to allow more flexibility in network design. He was a PhD student at the evil marxist Hitlerian academic bureacracy that is Stanford.
In 1983, the DoD made the TCP/IP stack part of the official networking standard for the US Government. Yep, those evil socialist military types, wasting your tax dollars by creating a completely useless standard.
In 1986, the National Science Foundation, a disgusting socialist waste of taxpayer dollars, created the NSFNet for science researchers to use to communicate data back and forth. It used TCP/IP and so was compatible with ARPANet. Then in 1987 the combined ARPANet/NSFNet was opened to commercial users - and the Internet was born.
That's great! We can all be glad that you were not able to stop that evil, socialist, Hitlerian Internet, since today that benefits both you and countless other students who use it for research.
