Garbage collection could be automated tomorrow if we wanted. Fast food is just a matter of us not trying hard enough but plumbers is a difficult one.
Not saying it couldn't happen. Two scenarios I could see are everyone lives in a prefab home, when things start to go wrong you just replace it. That leaves all the plumbing to just cutting and bending pipes to pre-built designs and installing it in prearranged steps. I could see that being possible.
Another interesting case could be that all houses are 3d printed, with cavities for plumbing printed right into the fabric of the building, and possibly sealed in someway.

Currently we live in Microsoft houses, eventually we might live in Apple houses. That is a terrifying thought either way...
