> fault-tolerance is included as a requirement by default for any sufficiently complex distributed system, but has little to do with the languages/frameworks used to build that system Erlang/Elixir have an extremely compelling story when it comes to fault-tolerance. You can only argue that all languages are created equal in this regard if you fall back to the "everything is Turing-complete so they're equivalent" argument. Erlang and its VM were built from the ground up to work closely together with fault tolerance in mind, in a context where a few minutes of downtime meant severe financial penalties.
