We do, however, have computer assisted plumbers, electricians, and other technicians. With nothing more than YouTube one can fix appliances and cars, or do some DIY home improvement, and the projects that are possible are much more involved than they were in the old days. It's very hard to pick up these skills from a book, but if there's a video to walk through the process - the projects become possible.

AI-assisted plumbers will follow this archetype.
