I didn't say it can't be reproduced in silicon. I said that LLMs can't model it, because they simply don't (yet) have the circuit / program for a model of interconnected abstract semantic concepts that our brains have.
Once this can be realized, there could be at least an emulation of intelligence, while I'd leave the discussion wether an emulation in silicon is completely equivalent to the biological model - say: personhood - to the philosophers.
