> POSIX won because it was first. Simple inertia keeps it there. UNIX only started wide distribution in 1975. The first POSIX standards were not proposed until 1988. To pretend otherwise is to attempt to rewrite history. There were complaints about UNIX API's long before everyone standardised on POSIX. Not before, not during, not after, have the elephant riders really gotten down and gotten to work. And where they have, as others have pointed out, it's things like io_uring which have emanated from the Linux community itself. Embedded API's may be better in many respects, but that does not mean that any particular vendor's implementation should be the new basis for a standard - especially if they cannot or will not support the existing deployments out there. Software developers love a clean slate, solution providers and integrators need to be able to deploy something to their customers and be able to guarantee interoperability etc. It's a pipe dream neutered by the practical reality of the real world. Nobody is arguing that they are completely wrong - it's just that it's long been giving off a "young man shouts at cloud" kind of smell for a long time, and it's not really that useful other than to give other people who have been hurt by POSIX a place to vent before they go off for another scrum, kanban, retrospective, or long lunch and forget about it until the next article.
