It’s the perfect Wimbledon. The sun is out, the Brits are firing and as for the scoring, that too will be somewhat perfect, this being the first Wimbledon since the tournament told the line judges, long the arbiters of accuracy, that after 148 years, their services will no longer be required.

Arguments, unpredictability and, as the cameras zoom in to the line judge whose eyesight judgment prompts a participant explosion, buttock-clenching awkwardness in close-up: goodbye to all that. Hello, AI and sharp-eyed robots, analysing in real time 18 lots of footage.

It’s perfect now, but is it progress? After the first day, players complained that while the calls were perfect in their accuracy, they were imperfect in that the gizmo’s volume was set too low and they could not hear the verdicts.

To some extent, Wimbledon is falling into line – both the Australian and US Opens, and very many of the lesser professional tournaments, have waved goodbye to the humans and embraced electronic line........
