The lack of intelligence lies in the fact that, for AI systems, you must first know what the structure of the activity to be modelled computationally is. Intelligence, as I think Piaget conceived of it (and he was by no means the first or last to see human beings in this way) requires insight, first into the empirical and functional data that needs to be modelled (for which there is, without falling into an infinite regression, no possibility of a computational approach in any mathematical sense), and then into the structures that are constructed by this process. The first allows us to say, 'this is what it really is', adn the latter enables us to add 'but that doesn't make sense'.

In other words, intelligence affords both insight and criticism. I cannot see any computational method for doing this, so if there is going to be any AI, it cannot be on a computational basis.
