Basically microservices over ip/dns are actors (maybe not pure actors like Carl Hewitt would insist - but close enough), so I think it's safe to say that the dominant programming model today is actors.

Having spent a bit of time in actor-land at the language level, I think the primary advantages of actors are:

1) making concurrency relatively easy to reason about (vs. say strict async/await, promises.. shudder, async/yield, whatever twisted does etc.).

2) more importantly, and most actor frameworks don't get this right, fault tolerance and isolated failure domains. If your actor system doesn't limit the blast radius of a failure, then it's missing one of the biggest reasons to go with actors.
