Unix history certainly has aspects of the "grandfather's axe". Few users of unixoid systems today are running original 70ies Unix code.

But Unix is not just code. The concepts introduced by Unix - or at least the flavor given to certain concepts - lives on to this day. Basically all of the userspace-kernel interface, the system calls, are still there and work in largely the same way. These concepts and interfaces are parts of the axe too and they haven't been replaced.
