I don't think anyone can guarantee what will or will not be automated in 10 years, let alone the 40+ year span that the average high school graduate can expect their career to last. That said, past trends hint at it being more likely that manual labor positions will be decreasingly lucrative as time goes on.

Well my dad's construction company is doing a lot more prefab in warehouses which is not only more efficient but removes hazard pay (elevation related). This would not be possible if not for the advances in BIM software.

Prefab, and technologies that reduce labor. It won't eliminate labor completely, but will reduce demand.

My house is full of copper plumbing, all cut and soldered together by hand. The wiring is all in hard conduit. Today, conduit is gone, and plumbers assemble things using flexible tubing and fittings that get squeezed onto the ends (for lack of the correct terminology).

I doubt that fixing things will ever provide as much work as construction.

Gonna send in the nanotechnology ;)

It’s more like you have a smart home with dozens of sensors and IoT devices that will have some self-healing capabilities. Don’t forget the always-on listening device and screen so you can be brainwashed daily.
