A free market sees the rise of unanticipated industries. We will see an emergence of robot-support technicians.
A teen can make some money flipping burgers but will make great money keeping the flipping robot running smoothly.
There are a lot more jobs than you think in regards to robots. Think engineering of how to get them to do what is needed. Engineering of components, and testing. Technical writing to describe their functions. Better ways to create joints and muscles, and how to miniature them. Then there are the electronics and portable power systems. The physical looks. And the AI software and communications. Tons of jobs available in regards to robots, and we aren't even talking about maintaining them running. Plus someone has to design and manufacture the pilot components. I've spent time watching my son-in-law design and repeatedly manufacture metal components on large CNC machines before settling on a design and sending it off to manufacturers. This stuff is done by humans, humans that don't need to flip burgers.
