You picked an example where the Job includes social interaction, which is a fundamental human need. Let's consider an assembly line worker who fastens the same set of screws over and over again. Do you still come to the same conclusion? Is a dull, repetitive job psychologically harmful over long times? There are jobs that greatly endanger people's physical health. Mining and construction come to my mind. If automation can make these jobs safer, go for it.
