UNIX can in fact be considered to be a 'simplified' successor to MULTICS.
Which is precisely why Unix matters and MULTICS doesn't. The simplifications in Unix are its most important contribution to the art of OS design. For example, we now take it for granted that the OS should implement a disk file as a simple byte stream, with bigger structures, such as records or indexes, being implemented on the application level. But when Unix appeared, that idea was novel and controversial."
Er, well, no actually. WHERE THE BLOODY HELL DO YOU THINK UNIX GOT THAT EXACT PARTICULAR IDEA FROM, GENIUS?
Score 5 Insightful, my arse.
This child, from the depths of its ignorance about Multics' interdependency with undocumented long-lost intelligent peripherals such as the FNP (front-end network processor) and IOM (I/O Multiplexer), by some fluke actually managed to state the exact problem. I will henceforth refer to such a process as 'aleatoric wisdom'.
The ongoing disevolution of computer science would appear to be some sort of immersive spinoff from The History of the World Backwards.
