Why are so cheap to replace a cameraman by an AI?
They could leave the camera control from remote to someone in a low income country, would make a better job for peanuts.
Latency: (cheap labour is usually far away from the match). This makes teleoperation harder.
Bandwidth (TV ops run from a van in a car park - so getting a reliable video feed out is expensive).
Logistics: you still need to hire, train and utilise that person effectively.
Reliability: what if your remote operator's internet goes down?
