Looks matter because it’s a place to live. Many commieblocks deal with that just fine by having the green space around them though. I kind of like the look of some of them though - solid, practical, maintainable. Some of the modern builds in my local city look more like temporary emergency shelters - like the people staying there don’t belong.

Looks like the ones in the picture are already surrounded by green spaces - they’re probably already pretty great as far as skyscrapers go.

They get moved to the init process (parent 1) if their original parent dies. The init process should always wait on its child processes so they’ll get cleaned up then. No reboot needed.

Once they’re zombies all they really exist for is to return an exit code for their parent - they’re no longer running.
