Clearly there isn't an answer that will make everyone happy. Like most fan bases, we spend an inordinate amount of time complaining how referees are tainted. That might be by the commish, or Vegas, or personal bias...but according to VN, every ref in every game has an agenda. You will never remove bias from a human ref. Ever.
A narrow AI has the potential to completely remove bias, but of course, then we've lost the "human" element. We've also lost the boogie man that we get to blame for everything that doesn't go our way, so that won't be popular.
I would say "pick your poison", but in the end it will get picked for you. If I were a bettin' man, I'd say it'll end up AI, but who knows. Digital music was too perfect, so now everyone is breaking out the record players and vinyl. I guess pops and crackles makes the music better, and perhaps biased officiating is an important part of the game.
