I'm beginning to join the unpopular position of letting technology call the strikes, not a human. It's real time, no delay, no bias, complete viewing coverage of the plate. Umpiring is becoming a "make-work" program. I don't hold this view in any strong way, but would love to hear the arguments on both sides. I guess one obstacle would be letting the catcher know in real time whether the pitch were a strike or not when runners are moving and on dropped third strikes. Would there be and immediate flash of light or sound indicating a strike -- like they have in tennis on serves to call it out? I dunno, but I think this eventually will happen.
