Far be it from me to argue against progress when we know how much humanity has benefitted from it. Language itself, the means by which we are discussing this topic, was a huge step forward.
That said, we are talking about a sport, not the internal combustion engine, the advances made in medicine, or the exploration of space.
Consider how much science and technology have changed--and changed our lives--since 1901 (advent of the AL) vs. how little baseball has changed.
Mounds are lower. The baseball is livelier. The DH. Foreign substances on the pitched ball have come and gone. Gloves are better. Bats are still wood, not aluminum, and about the same sizes/dimensions. Bases are about to get bigger, I think to prevent injuries. And pitch clocks are about to get serious--a massive intrusion which is probably necessary.
Nevertheless, watching a game in a ballpark today is very similar to watching one 111 years ago when four umpires were first used.
More to the point, think back to all the great games, World Series, records, players, etc you can remember or have read about. All of those wonderful moments were achieved in the context of fallible umpires, who were on the field when Don Larson pitched that perfect game, when Babe Ruth hit 60 dingers, when Ted Williams hit .406 in 1941, when Sandy Koufax was so brilliant for such a relatively short period, and when the Sox ended the Curse of the Bambino in 2004 and then won again in 2007, 2013, and 2018.
