Mutex Hell (Go/C++) where shared-state leads to subtle race conditions and deadlocks. The GC Ceiling (Erlang/Elixir) where you get a brilliant mental model, but pay for it in garbage collection pauses and VM...

There's another way to approach correctness: specify what the system should do, not how to do it — and let a computer program verify that all possible executions satisfy your requirement.
