A hammer isn't the equivalent of an AI. A 3d printer is much closer for comparison. And if you'll note, 3d printers have been used to build buildings of some note; and is perhaps a low level AI of sorts. China is planning on printing a dam for a river.
What used to take a whole team of humans with jobs, is now one or three people doing a design and pressing "print".
So effectively, yes, AI has destroyed those construction jobs. And note, those are all low level jobs for poor and working class. So that's who gets hurt the most in this scenario, working class people.
And as for your "smart hammer mounted to a robot"?
Using natural language processing and AI, PIBOT can perform takeoff, landing, cruise, and taxi tasks without any modifications to the plane itself.

In the end that would mean one single human builds a towering building downtown, whereas previously it took hundreds, if not thousands of humans to do this work. Maybe you can call this a win for efficiency but wow that is a lot of destroyed jobs.
Yes.
Destroyed. That is the correct word. Destroyed.
