The first three you listed are well on their way to being automated within a few decades. The last one seems out of place, since electricians are relatively well-paid and often self-employed. I think that we're seeing a gradual shift away from a service economy, mirroring earlier shifts from industrial and agricultural economies, as service jobs are automated or taken over by people in poorer countries. I'm not sure what to call the economy that's coming, though. A creative economy? A reputation economy? An economy where people work on the things they find interesting, and if other people find them interesting, too, they get paid. Many of the menial or boring jobs will be automated.
