As for the argument that professions like plumbers and electricians who physically visit their customers are not threatened by AI, this is not quite true.

For example, utility companies would send someone round to read our meter. Now they want us to have a smart meter (or, failing that, report our consumption online ourselves).

A current development in the automotive sector is toward systems that can be diagnosed and monitored automatically and remotely, and in some cases even fixed remotely, cutting out physical visits to a service centre. This will happen in other sectors as well.

Once your boiler or heat pump has enough sensors to monitor everything that could go wrong, physical visits will only be required once there is actually something that needs physically fixing. Etc.
