Yes, QNX predated Minix by several years, but Minix was completely

Have you talked to Andy and confirmed that? I'd be quite surprised if
he hadn't played with QNX but who knows. I wouldn't assume he hadn't.
And forgive me for asking, do you have some axe to grind against QNX
or something?
To me, it's not that surprising that the rest of the world didn't copy
QNX because the rest of the world was either a mono-kernel or it was
Mach. Don't get me started on Mach, it has defenders but I absolutely
hate it. Mach is more of a distributed research OS that advertised
itself as a microkernel. There is _nothing_ micro about Mach. It's
a big bloated mess.

I'm well aware that QNX has been extremely successful commercially and
can be found in a wide range of embedded systems. I'm specifically
talking about architectural influence on other OSes.
Minix? QNX predated that.
