$150k is about 2-3 manufacturing floor salaries for one year. I am quite certain many companies would prefer to buy a compliant robot slave that will never ask for a raise, take sick leave, or get demoralized than to pay 2-3 fulltime employees the value of their labor, only to have them leave for a better job 6 months later and have to train new ones all over again.

150k is the cost of a single employee 24/7 for one year. You might get twenty years out of it.

humans can only work 8-12 hours per day.
