"But technology only gets better." Technology is bounded by mathematical constraints, though. The more you constrain the number of faces you are scanning and you are looking for, the easier the task is. But when you're trying to pick out any of perhaps thousands of persons of interest across an input set that is, say, in the millions, the more impossible it becomes.
