No, it doesn’t.

Posix, in its multifarious forms, spent a lot of time just trying to catch up with Unix — let alone Computer Science. To start with, you have System V and Berkeley 4. Now let’s add sockets. Ooh, how about a bit of threading (let’s ignore the vast difference between user space threading and kernel space threading)?

Hey! Bash! That sounds like a good idea! Nobody sane uses it any more, but it merits a standard anyway!

Basically, Posix is, and always has been, backward-looking. It’s “you should have used this,” not “you are better off using this.”

Any Loon who quotes Posix (and Queef often references it, without even going into details — I sense that Posix, to Adam, is yet unto a Ghod as Leibnitz and Newton)

... is full of shit.
