Some years ago, when IBM was investing gazillions of dollars into Workplace
OS, it appeared that Mach might well "rule the world." If Workplace OS
"succeeded," then there would be:
a) A community of students learning to build MK stuff atop Mach,
b) Widespread understanding of Mach-like systems,
c) People porting Mach to anything looking like a reasonably modern CPU.
This of course comes in as a "win" for anyone wanting to build other stuff
(like Hurd) atop Mach-like systems.
Somewhat similar to the way that Linux benefited from using ISA/VLB/PCI
computer hardware that was primarily designed for use with WinTel systems.
If Linux had required expensive, custom-built hardware, it would have
Something that Linux has "shown the world" is that it's possible to make a
monolithic OS kernel about as portable as they thought microkernels would
be. It's turning out to be fairly straightforward to port Linux to new
CPUs, given a GCC code generator. (Note that NetBSD had already established
that this was plausible; Linux has the difference that intentions of
portability were an afterthought...)
