A lot of those jobs are in trade fields and have to do with working with the real world where things aren't designed with millimeter precision in mind, such as a leaky pipe under your nearly-century-old house, machining a one-off part for mounting the base of one of those robots so it can be set up to do work, or making new cabinets for your kitchen that will account for the fact the walls aren't quite squared. Or replacing a part on what in those 20-30 years from now will be a classic car. Or running new wiring to allow one of those robots to have a food supply the building wasn't originally designed for.
People are the reason we will always need people.
Computers, Electronics, and wrenching on my own cars were three things that helped me immensely when I decided to study Robotics after getting sick from solder fumes for the better part of a decade.
