Many people would not want to or can lift boxes all day, like people with back problems. The robot supervisor job could be appealing to more people. So it's not replacing but creating a different job which more people could work.
Isn't that the the end goal of technology? Those of us working in the technology field have had a hand in replacing labor since the first guy that figured out how to connect a plow to an ox.
Our hope, at least mine, is that we remove drudgery and difficulty from people's lives and create new jobs to replace the ones that are lost.
