It seems to me that every iteration of AI agent framework idea is taking us closer down the path to what is ultimately just an Actor framework where the mailbox is an AI agent instead of a code loop.

Someone should probably just cut out the middlemen and do exactly that. A mature Actor topology orchestrator with a set of node types varying from binary logic to full agentic loops would go a long way.

It might be more like Apache Storm than strictly an actor framework the more I think about it, but it's there somewhere.
