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.

Just like champagne only comes from the champagne region of France, true segmentation fault only comes from a linux program shitting itself.
Linux is the imposter here. Segmentation fault refers to how the PDP-(I forget) hardware organized memory. It comes from the original unix implementation which linux has never had any part of.
x86 and x86_64 still have segment registers so it's not exactly entirely archaic, but they're not really relevant so that doesnt change what you said. I dont have the exact details on who implemented segmentation first, so I cant elaborate on that.
