Actually, it shows your lack of intelligence that you cannot think of a single thing to improve in UNIX design.
This is not what I claim. Anything can be improved. I claim that no EXISTING system is better or even comparable.
That does not prove anything other than Plan9 did not gain significant momentum or developer interest.
The fact that Plan9 didn't reach wide acceptance, indeed, proves nothing.
The fact that Plan9 was never implemented in a way superior to modern Unix-like system, stands by itself.
LOL.. None of the currently popular OS has survived because of technical merits. Windows survived because of monopoly. Linux only became popular because it was free.
There are plenty of systems that are "free" in whatever meaning you use that word.
After that initial small level of success lots of Linux services companies have hired people to improve Linux and it has become quite good, but the primary reason it took off was that it was free and a "good enough" clone of UNIX. In a capitalist society, 'technical merits' are useless talking points in marketing brochures. Its like CPU Megahertz wars.
And if it wasn't Linux, it would be another Unix-like system. There were no alternatives, and there are unlikely to appear in a foreseeable future. Maybe 5-10 decades after Microsoft OS will be eradicated, there will be a worthwhile OS with a non-Unix design. Until then, it's all pointless mental masturbation, there is Microsoft and there are Unix-like systems. Everything else is specialized or irrelevant.
Where has anyone claimed that UNIX is satan? Are you high or something? The majority of the people that worked on NT have a UNIX background and they sought to improve it - Which they did.
Every time Microsoft tries to imitate a feature of a Unix-like OS, they do it terribly wrong. It demonstrates that Unix-like thinking is incompatible with Microsoft culture.
