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.

BeOS solved the issue of unresponsive GUIs in the 1990s. The GUI just must never run in the same thread as the logic.
while this is good on theory, when your CPU is being absolutely hammered, you need to re-adjust priorities to make a system responsive again, it's actually not a simple thing to do without a context aware scheduler. Even though EEVDF is pretty good, it still struggles some times
My PC with a 133MHz Pentium 1 processor was pretty responsive all the time back in the day. It's definitely a solved problem.
