POSIX is a millstone around the neck of the software industry.

If you wanted to do something really new in operating systems, you might think "POSIX is insecure" or "POSIX is bloated", etc. If you have a fundamentally different API though you have to write a whole new userspace. You're going to put in a POSIX personality so you can run bash and vim and nethack but once you do that you have the insecurity, bloat, etc.

POSIX is backwards in so many ways. It freezes in time the OS innovations of the 70s.

I have a conspiracy theory, unsupported by facts, that Richard Stallman secretly invented POSIX as a way to get the proprietary UNIX vendors to waste time on something whose only value was to make it easier for folks to port their apps to GNUUUUUUUU/Linux.

Stallman only invented the name “POSIX”, not the standard itself.

that's what Big POSIX wants you to think pal
