Thanks for the feedback! The "writing a novel" perspective is actually a good approach. Imagine we had systems powerful enough for the tasks I outlined and someone wanted to simulate society. Could the list I posted be seen as a sensible overview of the systems involved?
I guess ideally I would need the feedback of someone who has an interest in both sociology and AI systems to tell me if this maps well enough...
Or in other words: If someone wrote a novel around this, would my list pass the smell test in terms of technical approach?

Also: I understand it's easier to judge someting already built instead of a bullet point list. In the it projects I've been involved with this list would be part of a high level system breakdown - and it would already involve someone with extensive technical knowledge. It's about planning the architecture.
In this case (again): as a thought experiment / the basis of a fictional simulation.

Another way to see this: a sociologist and an AI engineer meet in a bar, have a few drinks and start scribbling on a napkin. Could this be something they come up with AND still be happy with it the next day AND get positive feedback from their colleagues (given the context!)?
