And all the other mainframe operating systems ... Most of the other big mainframe companies tried to emulate IBMs walled garden each had their own OS, their own (incompatible) networking system, their own compilers etc
Unix was great mostly because it was simple and you could port it to new hardware ... Prior to that it was in no hardware manufacturer's interest to release their OS into the wild, that didn't sell mainframes. Unix also released a generation of frustrated systems people who were not allowed to write kernel code unless they worked for a mainframe company
I always imagined an OS had to be really user hostile to have a movie villain named after it. IIRC, Alan Kay, Bonnie McBird's husband, worked for them and, probably, made some of his opinions clear to his wife.
It IS the most user hostile thing I ever seen running on a computer.
For the longest time I had my systems cat Syslog to an lpr... anytime someone did something, I’d hear a bzzzzzt. Usually about 5 times a day. Maybe a dozen. Then one morning I came into work and there was a whole box of paper on the floor and the printer is still bzzt, bzzt, bzzt... it was a hacker who had decided to follow some instructions he found on the web and hack my system. Every time he’d do something he’d erase his steps... but he never checked to see that all his movements were being printed!
