I am fine with this. For me, the "Human Element" should always be about the players on the field. Not the umpires personal opinions. Umpires have been around forever, so I understand the desire to let them stay, but their mistakes add nothing to the game, only subtracting. Adding a computer to determine balls and strikes won't prevent Fathers from taking their sons to baseball games anymore.
it would be a great idea but I don't know how practical it is. You'd have to have a chip in every ball, a chip in the plate, but then don't you also need some kind of reciever in the players uniforms?
