You know of course this is a topic of great interest for me :)

I believe that Erlang's key differentiator, which people should look
closely at is this:

- Fine grained process isolation

The motivation for the design was to build systems that can survive faults.

As a pragmatic functional language, Erlang lets you build such systems cheaply.

So you get systems that run effectively with less code, less testing,
and less maintenance.

I'd be curious how many people, based on their experience building
production Erlang systems, would agree or disagree with this.
