Guess I'm too old, as I don't like robo umps, mic'd up players, bat flips, pitch clocks, elbow guards, infield shifts, sabermetrics, SP only going 5 innings, disappearance of the bunt/SB and a lack of collisions at 2B and home plate.
Don't mind replays, for some reason though...
Age has nothing to do with it. I'm an old dude too! But I have seen what technology has done to make other sports better and more accurate, and that should be the goal. I don't like many of the things you've listed bat flips, SPs going 5, disappearance of the bunt/SBs) but they have nothing to do with implementing a tool to make a more accurate call. The title is "robot umpires" but that is not what it is. Think of this as an umpire tool (it's Artificial Intelligence plain and simple) to make their jobs easier and their calls more defensible. The umpire is still in control of HIS game.
