Be careful what you ask for. FIFA's Video assistant referee was supposed to banish controversial decisions in soccer matches forever. Instead, they simply replaced one form of controversial decisions with another.
I want the split second decision. It used to be that the ball would go into the net, you'd glance over at the linesman, see his flag down by his side, the ref indicates for a goal, the fans lose their minds. It would all happen in a second or two, now we have 4 minutes of video pedantry following every goal.
This idea that soccer is a 'flowing' game with minimal stoppages is very important to fans.
Ideally AI and goal line technology should solve this. If the computer knows where the ball and all the players are at all time, then checking if the ball crosses the line or if anybody was offside leading up to the goal should be instant.
Even offside has subjectivity, something we only discovered after we implemented video review. Could you accurately tell which pixel of shirt sleeve is an attacker's arm and which is shoulder? (Your arm can be offside because you can't legally score with it, shoulder vice versa)
We already have goal line technology for the ball crossing the line, it's totally instant, the ref has a device on his wrist which vibrates.
It does today, but the whole point of the AI would be to remove that subjectivity. Offside would be whatever the AI said is offside. Not saying this would necessarily be a good thing for the game, but it would remove the slow video review process and let referees instantly call goal/no goal.
