Linux really has come a long way
(lemmy.dbzer0.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Good catch, I guess that's mostly true, but Windows NT was an evolution of Windows that mainly got rid of the DOS legacy. Which after Windows NT ran on a compatibility layer, where Windows 3 ran on DOS directly.
It's a bit of a grey area. But I'd say windows NT was a continuation of Windows that shared almost the entire API from Windows 3.0.
The old "System n" OS was also called MAC OS. And the switch to OSX was a completely new OS where the old MAC OS software ran on a compatibility layer.
I guess it can be seen either way.
