Return to Internet (thing)
There are many things to be discussed on the topic of the "internet", and an exhaustive study of all the connotations and denotations of the "internet" is certainly beyond me, there is one aspect of the internet that I can address: its origins, and the purpose for its introduction.
Ironically, the internet has been a great source of both misinformation and the debunking of that information. And one of these pieces of information is the "urban myth" that the internet was created to survive a nuclear war, as well as the urban myth that that belief is merely an urban myth? Confused yet? Good.
The development of the internet can only be understood in context, and that context is the great development of computer technology between World War II and about 1973, the date of the Mansfield Amendment. Those were confusing years in the United States: there was a combination of peace and prosperity, together with paranoia and preparation for war. The United States government, through agencies including Defense, Energy and NASA, poured money into research, in corporations and universities. This research helped move technology forward, so that computing and information technology became commercially available, and the cycle fed on itself. But the keystone to the development was arguably always national security, and national security in the 1950s was arguably mostly in terms of nuclear war. So the background of any technology during this era was in some ways about nuclear war.
But then we get down to the specifics. The Internet, and even the Arpanet, were not designed all at once, and the specific technologies that make them up were designed at various points for various reasons. Sometimes, those reasons are not very clear.
As I said, there were many other technologies that had to exist before the internet did, and many or most of them came directly or indirectly out of military research. However, the evidence seems to be that the internet was not "built to order" to survive a nuclear war. However, it is inconceivable that military researchers, working in the 1950s and 1960s, could have been working on an intensive communications system and not be thinking about nuclear war. So, as with so much else on the internet, the truth value of the internet's origins and original purpose will remain debatable.
