Imagine there is a bug in the code or unhandled edge case, only exhibited on 0.01% transactions. Elixir/OTP handler dies on this edge case, supervisor spawns another worker, 99.99% of user transactions continue to be served. Programmer wakes up next morning, comes to work, reads the exception log, fixes this edge case, optionally hot-upgrades the code in production if it's easier than doing a full restart, problem solved. Other frameworks have to carefully implement the same semantics (that is, prevention of propagation of bad state/cascading failures). Elixir/OTP/Erlang come with it by default, and coding style encourages it.
