With the latest video technology and software (potentially with AI), so long as VAR is used for ofside decisions only, it should be possible to give virtually instantaneous feedback to the referee without any further human intervention. It is the conservative nature of the governing bodies that insist on this half cocked system with VAR assistants sitting looking at screens, drawing lines and then relying their own flawed assessment. Other offences (handball etc) should be left solely to the referee.
