Is the technology even reliable?!?!?

MLB has had the ability to implement this for years now. One of the common arguments against automatic balls and strikes is that we still can't count on the technology, which is a rather strange argument. We have planes that make thousands of imperceptible course directions accurately and without human contact. We have machines that fabricate transistors for CPUs so small that they are only a few atoms wide. We have mapped out the human genome, the very building blocks of our existence. Yet somehow, in baseball, identifying where a white sphere crosses a white pentagon a couple of feet away is some monumental technological challenge? Poppycock.
