Machines aren't rational at all. That is, they do not respond to reasons. Machine behaviour is only ever caused (i.e. syntactic), not reasoned. When a human follows a rule, for example as part of a bureaucracy, then our behaviour is merely caused. But we can also be given reasons to not follow the given rule. This is precisely why "I was just following orders" is not a valid defence; even soldiers are expected to use their reasoning to disobey illegal orders.
