“I could certainly use an AI plumber right now.”
I got a feeling replacing a journeyman plumber or electrician will be the last thing AI robots will be able to do, when you consider, being able to first observe the problem, analyzing it, coming up with a solution, getting the parts, having the dexterity to get into all sorts of difficult, weird places, handling lots of different tools, etc.
Building codes will change for efficiency.
Your bathroom will be replaced by a porta-potty.
