I wasn't very specific, but I'm just talking balls and strikes. I guess the calls at 1B could go robot, but that's not a major issue with me.
I think we'd still have an ump behind home plate to make calls at home and judge foul tips, catcher interference and other things I haven't thought of.
Having a computer call balls and strikes would not change the game that much, IMO.
This is not a hot topic to me, but that's my opinion.
