Or maybe the Linux Desktop (used by a couple of people) should use more code from the android project (which is the biggest OS on the Earth)
The latter has sane sandboxing, proper IPC, an app lifecycle that makes sense for embedded devices (an app in the background should only ever take CPU time if it has an explicit service with permission for that)
etc.
It doesn't have it, because this is like security. You either have it everywhere, or it doesn't matter.
Sure, the Linux kernel is very capable, but the "gnu" userspace doesn't make good use of its features. Android makes much better use and has a bunch of software that could be re-used on the former as well.
