What about a tax on machines in combination with an unconditional basic income? Right now the worker is the loser in this game. Why not make him the winner? With technology he is no longer forced to do boring work. Machines can do it much better.
I would expect a tax on machines, absolutely. Many possibilities will be floated: such as taxes, limiting how many hours per day a machine can operate, limiting which hours of the day a machine can operate, projecting human costs onto the machines (cost of health insurance, sick leave, vacation time, etc).
Organized labor will pull for machines being restrained to as much of an equal footing with human labor as possible. Whether that will actually happen or not, impossible to guess. I do expect various cities, jurisdictions, countries, etc. will try implementing various schemes though.
