With reference to Fig. 2.4 you state that "it quickly becomes clear that the lack of circular dependencies reduces the mental overhead". It seems to me this is a very central point of the actor model. So why not give us an opposing view to the figure that includes circular dependencies and thus visualizes the problems caused by these? THEN it really becomes clear, even visually.

Thanks for the feedback, an example here could definitely make it clearer. Whilst it's not a core concept of the actor model, in this scenario, by removing any possibility of circular references, it's made the whole application easier to understand since we have a linear flow through the application, as opposed to having a significant amount of co-ordination which might be required when sending data between two actors.
