Which was actually the computing environment of the early 1980s, at places like PARC, MIT (Athena), CMU (don’t remember the name of their system) as well as commercial systems like Apollo. None of which he ever mentions when touting Plan 9.

After 15 years of computing I was shocked when I realized that Sun machines kept all their data locally, ran sendmail etc. It seemed like such a huge step backwards in time.
