Indeed, without Unix there wouldn't have been the same rise of Mach, or the drive to
make a portable VMS, as there wouldn't be a C either.
Many of the leaked internal tools to build NT reflect that all the back office stuff was
on Xenix and VMS. Just as you can find mentions of emacs in the makefiles for NT, and how
their life would be in jeopardy for changing the tab indentions.
Unix had such an incredible impact on the market that without it everything would be
different.
Without Xenix micros would have continued to be snubbed by the high end crowd depriving
that critical jump from machines that cost more than a large house to personal space.
What would be the portable OS to rule them all? TripOS is the best I can imagine. BCPL
everywhere.

When Cutler did Mica and then NT OS-2 he did not care what the user interface was. Mica
was a pure uk and NT OS-2 was also, but by the time of the product it became a hybrid.
Putting a different user interface, be it DOS, OS/2, Unix, VMS or Windows was in the
kernel design.
