Not to pile on with the rebuttals, but Elixir/Erlang are actually truly parallel. There wouldn't be much point to all the interest into it unless they were. You should go to the phoenix framework website for statistics on how it handles many connections and processes.
Of course, true parallelism only comes with multicore CPUs anyways, and this is what the Erlang VM ("BEAM") is geared to. The processes are not threads in the C++ sense and there is no shared memory, but there are separate BEAMs for each CPU core and the processes are scheduled to them. Message passing in the Actor style takes the place of shared memory.
