Here is one place:
Ultimately all intelligence may be absorbed into one super universal singleton intelligence.
If there are any kind of meaningful resource constraints, and of course there will be because we live in a limited universe, then you will need to give different contexts to your AI to solve different problems. By giving it different contexts you are effectively making lots of specialised intelligences, not one universal singleton intelligence.
You said “However, many real-world scenarios(including most social interactions) are affected by our thoughts, not just our external actions”.
I‘m not sure we accept this is true without further justification. I think this is important because it requires a more rigorous definition of what you mean by an action.
My prior definition of a belief is something held internally, while actions are the set of causal pathways by which one can influence the external world. With these definitions, beliefs can only influence interactions by influencing actions. Is this your definition, or are you defining these things differently?
