No, probably not, as much as I would love to, because there are still people who believe that POSIX's design ideals are to be aspired to, even as the world has aged heavily around them. The POSIX model and philosophies are very outdated, but as long as people see value in the nonsense that is "everything is a file" (except for all of the ones that you can only ioctl to) or "do one thing and do it well" (except text parsing, that famously secure and not at all haunted thing apparently belongs in every app), we won't see big shifts in production OS architecture. Maybe research kernels, but those don't run PostgreSQL installs.

I don't think that has anything to do with this complacency, however.
