What is interesting about Mach to me. Is that now 40 years later it's returning too it's roots of hosting multiple OS's on a single hardware architecture. Apple being able to design to M series chips to match Mach's paper over Mach's deficiencies and leverage it's strength I find very exciting. Originally it was meant to be the foundation computing layer for a campus full of devices.
