I find it incredibly useful - instead of needing to learn a million quirks about the init of every distro they all use the same predictable system now, you learn it's quirks once and those skills transfer everywhere. Hopping from Ubuntu to Debian to Arch to Fedora is trivial now compared to the old days.
That and systemd-boot and systemd-nspawn are awesome.
Linux has also overshadowed BSD. Diversity matters, but so do standards. Code interaction contracts (think APIs and syscalls) are the glue to make a program that will run on a lot of diffrent software/hardware stacks (like diffrent OSes and hardware combinations). Sadly specific implementation diffrences make the genaric contracts (like UNIX/POSIX) unable to be implemented pefectly.

Let me guess: travelling for you as an American have never been so easy since English today is a must-know virtually everywhere. What's the point though?

Autistic, right-wing conservative or just not much of a learner? The first one I understand, but the other two are just urging you to be pissed upon.
