The problem started when Intel published the handbooks for the 8086 with many thing 'reserved for future use' but nobody cared. Intel used segments to separate things everybody hated. Intel introduced later the rings, everybody ignored. Instead of keeping the things separated - as suggested by Intel's design - people used shortcuts whenever possible. People would have had to think a bit more those days. But Darwin was not sleeping and people have to think now. > this stuff is just so hellishly complex nowadays that no single human > can grasp and hold even a significant fraction of these things in Because it is all mixed up as a huge mess instead of being separated like Intel suggested in the Seventies and Eighties. > P.S.
