Neither are business owners, who make the decisions within enterprise, about how workers use enterprise.
If business owners decide that engineers would design machines, that factory workers would then build, and that sewer cleaners would then utilize, then the events may occur. Otherwise, not, and the determining force is the profit motive, not the will of workers.
The straw man you attacked was my alleged claim that no automation is ever profitable.
In fact, at any particular time, some automation may be profitable, and some automation may not be profitable.
