I started to notice a intense automation and Artificial Intelligence Investments from companies and that made me wonder, what would happen or what should be done with the people who can’t be trained for a new job and can’t use his current skills to to get a job.
How would he live or what would he do in life? More importantly, what should be done with him to make him useful or at least neutral rather than being a negative on the society?
Your statement is mostly false, despite your valid examples. Wealth/income requires people/consumers. Phones/computers are cheap because billions can afford it. Food profits is a function of people. Autos definitely require scale, that is far more efficient than a humanoid robot doing flexible “manual” labour.
At the same time, however, not requiring slaves does motivate genocide instead of just sharing wealth with the slaves. It’s better to exterminate humanity than to deal with slave class uppitiness.
