It can't even count reliably. And this is a computer, not a human. That is one of the simplest things a computer should be able to do. It can't count because it doesn't know what counting is, not because it's unreliable in the way a human would be when counting. You cannot reason if you do not understand the concepts you are working with. The result is not the measure of success here, because it is good at mimicking, but when it fails at such a basic computing task, you can reasonably conclude it has no idea what it's doing.
