> I see this repeated a lot but it's just not accurate. E-mail was invented within like 2 years of the internet and immediately allowed universities to exchange messages with one another. This is untrue. Look at my answer here https://news.ycombinator.com/item?id=29847559 https://news.ycombinator.com/item?id=29847559 .

But still, the point is that even ARPANET solved real problems: instant message exchange in text form, without the need for specialized telegraph operators, is a real problem with real value for anyone who can afford it - even at the scale of ARPANET.

  That was being done by teleprinters, from the late 1800s. The UNIX concept of the TTY comes from teleprinters and teletype.

But it is true. It is pretty clear that "Internet" in this context means "ARPANET", built in 1969. First email was sent over ARPANET in 1971. ARPANET was built to solve a very real and clearly defined problem - connecting computers over a shared network. Here's the original problem statement: For each of these three terminals, I had three different sets of user commands. So if I was talking online with someone at S.D.C. and I wanted to talk to someone I knew at Berkeley or M.I.T. about this, I had to get up from the S.D.C. terminal, go over and log into the other terminal and get in touch with them.... I said, oh man, it's obvious what to do: If you have these three terminals, there ought to be one terminal that goes anywhere you want to go where you have interactive computing. That idea is the ARPAnet. Source: https://en.wikipedia.org/wiki/History_of_the_Internet#ARPANET https://en.wikipedia.org/wiki/History_of_the_Internet#ARPANE... To me it seems like crypto still hasn't found its killer application, 13 years after its creation.
