The article below from Slow News goes around. I think it makes quite a point. Yoo Hyunjin complained about the strike zone. But
This needs to be considered over data. This is because there is a basic human bias. Machines also malfunction. There are cases where the malfunction is absurd, so they blame the machine, but overall, it will be significantly less compared to human judgment mistakes.

Even with the current autonomous driving technology, I think it's safer than driving by humans. The probability of an accident is lower. But there is a high possibility of a ridiculous accident. But statistically, if you put it all together and calculate it, I think it will be better than humans. If a ridiculous accident is a human, the likelihood of it occurring is almost zero, but I don't think the machine can replace a human because of the possibility of it occurring due to a malfunction of the machine.

Baseball also needs to open up all data. And you can modify it. But it will be more accurate than humans. The reason is not so much a human limitation as a matter of convenience.
======================================

The automatic ball judgment system (ABS) has been introduced in the professional baseball league. It is a machine umpire.
"Until now, elite bias has worked in strike zones," said Lee Yong-kyun, sports director at Kyunghyang Shinmun. Chances were high that a ball that was difficult to throw would be judged as a strike, and a ball thrown in the opposite direction to the catcher's signature was often judged as a ball even if it passed through the strike zone. The catcher's ability to hold a ball to make it look like a strike was also recognized as a highly sophisticated technique.
The strike zone widened when it was 3 balls + 0 strikes, and the strike zone narrowed when it was 0 balls + 2 strikes.
However, when the machine saw the referee, all of this bias disappeared. Among the top 30 hitters in the on-base percentage, the number of hitters aged 30 or older has decreased and the number of hitters aged 25 or older has increased. Pitchers also made remarkable strides under the age of 25.
