8. The "Artificial Intelligence" argument Materialists conclude: - The advanced supercomputer is behaviourally just like a human - The supercomputer doesn’t have a mind- Therefore humans don’t have minds either Dualists argue: - The advanced supercomputer is behaviourally just like a human- We humans clearly embody minds, so - The supercomputer must embody a mind as well.
