there are a handful of jobs that you probably can't automate at our current level of development of course. kitchen staff, cleaning staff. youre gonna need these no matter what. robots can make those jobs easier right now but it doesnt get rid of them. customer service is also likely unavoidable, though a lot of it can be automated with a sophisticated enough robotic q&a. some people claim transportation industry is also a service industry, if that were the case you could just invest heavily in trains and cut something like 3 million jobs from tractor trailer drivers if you have good infrastructure set up.
