I fondly remember Joe Armstrong, who was a good friend.

However, not having a mathematical foundation has been a

severe limitation for Erlang.

The Erlang community is trying to dig its way out with

modifications and extensions. Still have a long way to go.

Of course, no Actors framework is perfect.

Many important implementations have been done Erlang.

Also, significant Erlang projects are ongoing to good effect.
