That also makes the assumption that there is only one "technologically most useful solution", when in practice every application has its own unique requirements, and trying to satisfy all of them just makes a system which is not particularly good at any one of them (systemd seems to be moving in that direction, not unlike other "enterprise" software.)
And that is why Unix as a concept has endured even in the face of opposition like Windows.
Because at its heart is a collection of tools that can be combined in whatever permutation that solves the task that the system user/admin has before him.
