It's never going to get any better mate because as you said, its humans behind the screens who are just as bad as the ref on the field. Not only that, we then have idiots who have researched all this for years and made a total mockery off it.
Millions of people for centuries have loved football how it was, despite the odd mistake by a referee. All I'm saying is keep the technology to goal line and offsides and things would be much better than they are now.
