 As it stands, what we have here is not an argument against the claim that machines can think; rather, we have the expression of various fears about what might follow if there were thinking machines. Someone who took these worries seriously—and who was persuaded that it is indeed possible for us to construct thinking machines—might well think that we have here reasons for giving up on the project of attempting to construct thinking machines. However, it would be a major task—which we do not intend to pursue here—to determine whether there really are any good reasons for taking these worries seriously.
