ARPANET, the direct predecessor for the internet, was created for collaborating, including socializing and reading. It was NOT created to "have a war-proof network for army use". The latter is a pernicious falsehood.
Quoting https://en.wikipedia.org/wiki/ARPANET :
> It was from the RAND study that the false rumor started, claiming that the ARPANET was somehow related to building a network resistant to nuclear war. This was never true of the ARPANET, but was an aspect of the earlier RAND study of secure communication. The later work on internetworking did emphasize robustness and survivability, including the capability to withstand losses of large portions of the underlying networks.[51]
See also Licklider's work with https://en.wikipedia.org/wiki/Intergalactic_Computer_Network leading up to ARPANET, or his "The Computer as a Communications Device" - https://signallake.com/innovation/LickliderApr68.pdf where he describes how the network might be used:
> You will not send a letter or a telegram; you will simply identify the people whose files should be linked to yours and the parts to which they should be linked-and perhaps specify a coefficient of urgency. You will seldom make a telephone call; you will ask the network to link your consoles together,You will seldom make a purely business trip, because linking consoles will be so much more efficient. When you do visit another person with the object of intellectual communication, you and he will sit at a two-place console and interact as much through it as face to face. If our extrapolation from Doug Engelbart’s meeting proves correct, you will spend much more time in computer-facilitated teleconferences and much less en route to meetings.
and has a section titled "On-line interactive communities":
> Available within the network will be functions and services to which you subscribe on a regular basis and others that you call for when you need them.In the former group will be investment guidance, tax counseling, selective dissemination of information in your field of specialization, announcement of cultural, sport, and entertainment events that fit your interests, etc. In the latter group will be dictionaries, encyclopedias, indexes, catalogues, edit-ing programs, teaching programs, testing programs, programming systems, data bases, and—most important—communication, display, and modeling programs.
Collaboration and reading were surely some of the main goals in the vision that became ARPANET.
