Last year I wrote a simple system using Semantic Kernel, backed by functions inside Microsoft Orleans, which for the most part was a business logic DSL processor by LLM. Your business logic was just text, and you gave it the operation as text.

Nothing could be relied upon to be deterministic, it was so funny to see it try to do operations.

Recently I re-ran it with newer models and was drastically better, especially with temperature tweaks.

When you put it like that it really is a bad product.

Great response. All arguments are valid and fair.

What's the technology behind this. I'm working on something myself, using a distributed actor model (setup like a graph) to create a living reactive model.

My sentiments exactly - well said. The big mistake is forcing OOP onto everything. It's why I really have an affinity with the virtual actor, it has just enough OOP for me to have classes, methods and internal state - I don't need inheritance, polymorphism, etc - just naive little classifications of things we call objects.

I also don't have to think of my system in a hierarchical supervised manner like earlier actor models. I just need cloud native distributed little objects.

You can see some modern products coming out that are just that:

2. Restate Virtual Objects - https://restate.dev/

I agree. I'm not advocating doing a purist DDD solution but rather using similar modelling techniques and just making naive actors.

It's just part 1. I have just published part 2 which goes into more detail.

That's fair feedback. I wanted to post it in 3 parts, but I see now I probably should have just made one large post.

As I mentioned there's nothing novel in this post, especially for a senior. This is more about getting some context out of the way so that I can show some techniques in a future post.

It's tricky to provide a really good example right now. I notice in the .NET world there are like these DDD "starter packs", and my god, they're just layers of maintainability hell. If you look at older OOP/DDD books you'll notice that the domain object has real world methods on it, just like as if it were from a UML diagram.

What you should end up with are plain OOPy objects that mirror the real world. They're not skewed or constrained by their database model. They shouldn't have any dependencies on your infrastructure layer. The object should encapsulate state, behaviour, validity and consistency.

An example (which is probably overkill) would be https://learn.microsoft.com/en-us/dotnet/architecture/micros...

The next post is about modelling an actor and it might provide more insight for you.

What if the platform is not registered as a business in Australia? You can't fine it if it's not a legal entity there. Simply setup a php Facebook clone and host it in another country.
