There are plenty of existing jobs where people have to spend many hours by themselves. Think about truck drivers, they may spend weeks alone with nothing more than a few minutes chat to a fellow trucker they see at a truck stop.
That‘s not true. Truckers have radios (at least in Europe) and they they are interacting with other truckers in radius of ~10 miles. I had radio in my car and and it was even entertaining sometimes. I could ask advice, ask for fuel when I was empty, ask for police checkpoints. On private channel one can have virtually private conversation.
We should invent something like that, 'radio', thing for computers
Those solo jobs are a small minority of the workforce.
Trucking is the single largest job category in the US
truckers are outside, travelling, visiting places, constantly exposed to different circumstances and people.
