I understand that they aren't going to deploy some cyborg-esque statue behind the back catcher to call balls and strikes. I enjoy the way the game is played now and much prefer the human element as opposed to a robotic one. Plus, there will be huge resistance from the Players and Umpires alike. I don't see it happening and hope it never comes to fruition.
This is coming from someone who will probably never get over the strike called on Ben Revere vs KC in the ALCS. It's part of the game.
