It seems that way because AI keeps getting redefined as what we haven't figured out yet. If you told some ancient Arabic scholar that, in the modern day, we can build things out of mostly metal and oil and sand that have enough knowledge of medicine or astronomy or chess or even just math to compete with the greatest human experts, machines that can plot a route across a convoluted city or stumble but remain standing when kicked or recognize different people by looking at their faces or the way they walk, he'd think we have that "homunculus" business pretty much under control.
