I'm a huge fan of the actor model and message passing, so you do not have to sell it to me; I also strongly dislike the current async fad.
But message passing is not a panacea. Sometimes shared mutable state is the solution that is simplest to implement and reason about. If you think about it what are database if not shared mutable state, and they have been widely successful. The key is of course proper concurrency control abstractions.
