In Spain and Mexico there are still people who ride around playing a particular flute melody on a bike equipped with a fly wheel sharpening stone.
People bring out their knives to the front of their homes to get them sharpened.
Its odd that this is still needed. Those guys sharpen the HELL out of any knife in seconds though, I guess thats why.

Blacksmiths still make horse shoes though they don't care for horses feet or put them on anymore.

With all the talk about autonomous vehicles these days, I've been wondering something: why aren't trains fully automated by now? Why do railroads still employ engineers to drive trains around? I assume unions are the main reason.
Compared to cars or trucks, automating a train is trivial. I mean, there's no steering involved on a train, just forward & reverse, which simplifies things immensely. Switching tracks is already handled remotely, and there are already systems in place to track train movement and prevent collisions. For precise movements, like coupling to cars, the engine could be piloted remotely like a drone. For long-haul work, the engine would largely take care of itself between stops. Acceleration sensors could detect any problems, and stop the train and/or signal an emergency to the human monitors. The only real issue I see is people/animals/obstacles on the track, but even with human control there really isn't much the engineer can do except blow the horn. Trains are just too big & heavy to stop quickly.
So now I'm wondering, are there any other jobs that ATS members are surprised still exist?
