my (possibly dumb) personal "conspiracy theory": some time in the relatively recent future there is going to be The Grand Linux Userspace Fork. There's going to be "SystemD with the Linux Kernel" (the SystemD system with Gnu utilities and the Linux kernel if you're into that sort of thing) and then "classic Linux", which is just "not using SystemD".
We already sorta have this now. What I'm (half-jokingly) suggesting is a big ugly fork a la Emacs/XEmacs, where the world visibly and somewhat incompatibly separates.
And like that fork we'll end up with everything more-or-less reconciling eventually, but it's going a weird ride until then.
