This thread raises a legitimate point, please don't clutter it with tangentially pointless posts. Personally, I don't think the technology is in place to be able to replace umpires yet. Even stuff like pitch f/x misses pitches with some frequency, and without any human presence the slightest malfunction could be disastrous. Plus there's plenty of judgment calls to be made still, like check swings, balks, and safe/out(again, technology isn't there yet, or technically it is but would slow the game to an insane degree), interference, etc. I'm all for raising the amount of correct calls though, I have no attachment to the "human element" as you call it. It's just not very feasible yet.
