The brain starts with the semantics. Some are innate, others are learned, but the semantics is always first. The syntax is then layered on top of this. This is why the high-intelligence end of the autistic spectrum is linked to delayed speech followed by a very rapid process to complex speech. The semantics is being built to a far higher degree, the syntax is postponed until the last possible moment.
AI, as it currently exists, needs a very very large number of examples, far more than the brain by tens of orders of magnitude, and hallucinates far more, because ALL it knows is the syntax. There is no handling of the semantics at all.
This approach can NEVER lead to actual intelligence of any sort, let alone superintelligence. They are solving the wrong problem. And that is why they fail, and why they will only ever fail.
If you want actual intelligence, the syntax must come LAST. And the modern breed of AI researcher is simply far too stubborn and arrogant to fathom that.
