Don't know if you care this much or not, but figured I'd link this Elixir talk that goes into details regarding hot upgrades. https://www.youtube.com/watch?v=I

  That’s a great link thanks! It really makes it clear that a) correct state changes aren’t automatically correct (there’s both a manual and automated piece and either can go wrong) b) while the language makes it possible, there’s still a lot of manual work involved & footguns (e.g. if you have a contended resource held while something is being migrated, you’re going to experience degraded availability for other sessions to the point of downtime).
