For anyone interested in a deeper dive into the foundations of the Actor Model, I highly recommend this entertaining 45-minute explainer by Carl Hewitt, one of the model’s original pioneers: ▶ this video

May he RIP. I first heard about Hewitt after watching this[0] conversation about the actor model. It's truly a masterclass. For those who want to learn more about the actor model, or simply have a fond memory of ProfHewitt, I highly recommend it. [0] - ▶ this video

I'm sorry to go completely off-topic here, but I just wanted to say thank you! Your discussion[0] with Meijer and Szyperski was mind-blowing and taught me a lot about the actor model. This was, hands down, one of the best classes I've ever had. Thanks for sharing this knowledge. [0] - ▶ this video

> so different in an actor vs a queue with workers In short: different computational model -- Actor model vs. Communicating sequential processes. This really helped me: ▶ this video Edit: added link to video

Absolutely I would. Everyone has their opinion about Microsofts products, but the platform and frameworks that underpin them are rock solid, long-time battle-tested in production, and easy to work with as a developer. A .net stack comes with the comforting knowledge that this technology will never be made obsolete. It will undergo active development and will have support for many years to come. One day, long into the future, it will be super seeded by something else. When that happens, you know there will be a migration path because Microsoft has based their own business on it, and they need it for themselves, and all of their customers need it. .net does not go away tomorrow because something shinier showed up. That's nice to know. You will find that you will have a very stable and mature stack that is well integrated with Azure making deployment and testing easy. Was I to build a microservice application, I would not choose Kubernetes. I would choose the Microsoft Service Fabric Actor model over anything else that is out there. Service Fabric is Microsoft Secret Sause. It is the technology that underpins the Azure Platform itself. Service Fabric has a beautiful actor model that makes the development of cloud-based applications as simple as writing a single threaded console application.

What do you think about hierarchical state machine [1] ? >Has it already been through state X? Like everything else, logging >Will it come back to this state in the future? Mentioned in the comment before, there is a transition graph that you can do static analysis on, note that you might run into a halting problem >Is there a route from state Y to state Z? There is a transition graph >State machines are effectively goto writ large... quoting Prof Carl Hewitt of Actor Model, "goto is harmless"[2], function/procedure call is a goto, much like sending an named event while in particular state with/out parameters [1] [link] [2] ▶ this video note: edited for formatting

Indeed, Joe Armstrong once said that he believes Erlang to be the only OO language according to Alan Kay's idea [1]. Also, let's not forget to give credit to Carl Hewitt who came up with actors in the first place [2]. [1] [link] [2] ▶ this video
