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.

Not buying it. The colossal attack surface of a giant monolithic kernel should not be controlling an automobile. No offense to Linux or anyone who works on it, it's great, you just can't rely on it with your life. It was never designed to be.
I come from a MCU background and feel the same way. Linux kernel is for consumer level stuff. For serious machinery, I choose a real-time OS like FreeaRTOS. Less code, and more low level code makes it easier to review, maintain, and have less chance to break.
Ive been seeing Linux take a more controler of controllers kind of role. Handling updates, networking, complex logic, logging, metric, etc.
It'll be interesting to see where it goes. On one hand ASICs, FPGAs, and microcontroller are getting easier than ever to program, its still not as easier as having a full Linux OS to build on.
