Effective aggression and ring generalship are subjective human judgements. Boxing results are varied because in a championship fight, many times rounds will be completely subjective.
If you made boxing judged by AI, the rules would quickly be gamed. I suspect it would turn into a contest of jab/output and completely ruin boxing.
What ultimately makes boxing great is a fight today doesn't look that much different than a fight 100 years ago. That is the whole fun of it.
It is a really a symptom of a culture obsessed with scientism. As if adding a bullshit layer of scientism makes things somehow better and "smarter".
