Now you mix User-space programs with kernels, we talked about Operating-system (Unix), if you see it like that Windows or Linux is the most modern OS, because most Software.
>explored the idea of Java based kernel drivers
They even made a Java OS a Browser and a Chip, we all know what a stupid decision that was, you could have say ZFS which is against the unix philosophy (one program one job) but you forgot that i think.
>Irix had Inventor.
Windows had paint, and Mac the almighty HyperCard...but that's NOT the Operating-system nor does it make any difference Unix-wise.
>NeXT had the mach kernel, drivers written in Objective-C
Ahh, now you bring the kernel argument i already brought, yeah drivers written in the beloved Objective-C (is that a feature or a User-space thing?)...you know Multics was made with EPL waaay earlier.
They are pure and certified Unixes (not NeXT, but MacOS X is/was), based on Unix ideas..basta.
Irix had Inventor.
NeXT had the mach kernel, drivers written in Objective-C, Renderman, EOF, WebObjects, DisplayPostscript.
Ridiculous is putting up with certain clueless people online that don't have any idea of what they are talking about.
