> Back in 1972, the goal was to be as fast and efficient as possible. Hackers weren’t a concern since computers weren’t connected.

On the contrary, one of the reasons Multics got a higher security score than UNIX when analysed by DoD was caring about security with PL/I.

Also remember Sun's "The network is the computer", and the Morris worm in 1985 as UNIX started to be widespread across university campus.

Ah, and the failure to add fat pointers to C, as Dennis Ritchie proposal wasn't taken by WG14, nor improved upon.

C authors followed their own path with Alef, Limbo, and finally Go.
