Yeah, and humans like new technology, even back then. If the steam engine could have called balls and strikes they would have had one plopped behind home plate in every ballpark in America. People went nuts for the steam engine. But even more than technology, people like things being fair, equal and accurate. At the game's inception, umpires called balls and strikes out of neccessity, obviously if they had the technology they would have used it; baseball wouldn't be the sole institution that would eschew it. No one laments the loss of blacksmiths any longer.
