[ih] How Plato Influenced the Internet

[Vint Cerf]

I worked on ARPANET from 1968-1972 and then started on Internet in 1973. I
joined ARPA in 1976 and stayed there working on Internet until end of 1982.
I visited the campus, met with Don Bitzer in the late 1960s (hazy memory),
was impressed by the display technology, but, honestly, do not recall much
influence on the Internet work. It was certainly an example of time-shared
application that could be expanded by way of networks like ARPANET and
Internet but I don't recall direct influence on, e.g., protocol
development, packet switch design, application layer protocols.
