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.

I feel like an important thing he forgot to mention though is that it lets you allow multiple users to have root privileges without having to share passwords or SSH keys
Indeed useful to not having to share passwords. I think sudo historically started as a way to let some users in a company for example manage printer server settings without having a root password. (And I believe it was Ubuntu in 2004 which promoted sudo and forced the default user after an installation to use sudo to perform root commands).
Why would they need to share ssh keys? Ssh will happily accept dozens of allowed keys.
Oh true yeah I always forget about that
