From the owners' (shareholders') point of view, managers are on their side to extract values from workers. Of course there are more nuances in real life, but that's a more plausible explanation than any of the meritocracy ones.
Hello, fellow Dickhead! Autonomous weapons working beyond their creators is a constant recurring theme, even features in one of his first few short stories: The Gun by PKD in 1952.
My theory of military bed making is that originally they had to grab the sheets and go on a very short notice, so it makes sense to "pre-pack" them. However, it gradually evolved into a performative art.
However, the conventional wisdom is to split the potentially reusable part as a library package and the executable to be a thin layer on top of that library.
In this way, for example, testing can just depend on that library. In the future, if there are requests that calls for a separate executable, the library can be reused.
Now there's the "pure" HarmonyOS (previously known as HarmonyOS NEXT) that most recent Huawei phones now have preinstalled (at least as an option for foreign markets). It doesn't have AOSP or Linux kernel and thus no compatibility. It just runs native apps (HAP).
Then, historically there's also a commercial version based on AOSP but removed Google services. You could buy it in a store back then, and it's compatible with Android apps that don't require Google services (up to a certain version?) Most Chinese apps don't rely on Google services in the first place.
There's also the open source version OpenHarmony. It was never commercially available. It uses the Linux kernel without AOSP. I believe part of it was used for the pure HarmonyOS development. It's said that the micro-kernel architecture was preserved for the pure HarmonyOS, which is quite interesting.
oolong means "black loong" or black dragons, referring to the tea leaves' color change during fermentation.
