I would argue that starting with the actor paradigm is better than starting with microservices (ideally with some form of dependency injection). In a way they are the same thing, but you aren't forced by the Actor paradigm to start with individual processes. You can start with a single service, and break actors out into microservices as needed. Starting with microservices seems like premature optimization to me. I feel that the actor paradigm fills this gap nicely.
