A big reason that AI threatens humans in terms of labor is how taxation is done right now -- AI is a capital expense, and can reduce tax costs. Human labor is very expensive, partially because of paying humans, but also partially because of a huge burden of payroll taxes.

I'd suspect that AI replacement of human labor would be delayed significantly by simply removing payroll+income taxes, and instead taxing capital investments and/or corporate profits instead.

Right now, any improvement that AI and machine labor provides is heavily subsidized by the population -- from the company's perspective, it's an artificially cheap source of production.
