...^^^ this is part of problem with today's society and its woefully misguided "technology" run amok. Just because we CAN do something does not necessarily mean we SHOULD do something. Our technology is rapidly outdistancing our mental ability to use it where it's needed most and our new "smart" technology is gradually making us "dumb".
... And the height of the strike was not only one reason why IMO, we're not ready to arbitrarily use "robots". Robot Umps may be the future of Baseball but not right now because there are still way too many questions and concerns to consider......what's next, robots replacing players?
...and your reference to "translation issues for call ups" for umpires also applies to young players/batter just as well which is the reason I said I'd rather it be started in the Minors.
...over the course of 162 games, I think things even out and pitchers getting squeezed are probably equal to batters getting squeezed.
...for the foreseeable future at least, I think that "pitchFX" and technology like it, should continue to be used to "umpire the Umpires", as it has for several years now. Because believe it or not, since these teaching tools have been implemented circa 2008, Umps have actually gotten better at calling balls and strikes.
...but for now, this subject is little more than fodder for "office water cooler" and message board discussions.
