Instead of answering on the technical merits of an argument, you went for an ad hominem so...? I ask again...do you use NIFs ?

"If the entire computer crashes, you're screwed. you can't really do fault tolerant computation from one machine."

      - Joe Armstrong

And the reason for the quote above is to remind you Erlang/BEAM gives you tools for fault containment and recovery, but not immunity from failure.

Say: Well-designed Erlang systems can fail gracefully and self-heal locally...but they’re only as fault-tolerant as their distributed architecture and ops discipline allows...And we will conclude in a nice agreement. :-)
