The technology can and will improve (and already has - see for example the availability of [semi-]automated offside).I can't agree. The system was implemented in the PL in 2019. It isn't going to improve.
What's holding it back from improving leaps and bounds as a system is people. And all it will take for that blocker to be removed is for some of those people to be changed and/or come to a decision that they want the system to be better and to listen to feedback about how to make it better.
There's currently nothing preventing it from improving that can't be removed and facilitate improvement as a result of the removal. It just needs someone with the power to do so to remove the blockage.
