It's also harder to write abjectly wrong code in the BEAM. I found out that my code was effectively self-forkbombing, because I had hooked up an error reporter (I adapted myself because the version I wanted had bitrotted) to rollbar which (very rarely, when the service was in outage) cause a crash, which would try to report, crash, and exponentially grow. Amazingly, this caused no service degradation for our customers.
