Another thing that's changed is engineering. The US has moved up the stack. Engineering is now mostly software development and within that it's mostly web development. Engineering and manufacturing has largely moved overseas to Asia and that's where most of the expertise lies. The only thing off the top of my head that the US still dominates in engineering is software/aerospace/defense. In general though everything else is dominated by Asia, if you want the top hardware technology the US is no longer the place to get it. In Silicon Valley there used to be a good mix of different types of engineers, now everyone is SWE, and most likely doing web stuff. But here's the thing, you most likely wouldn't have noticed this unless you thought hard about it because either you're too young or because the change happened so slowly.

The same will be for AGI if it comes into fruition. A lot of jobs will be replaced, slowly. Then when AGI replacement reaches saturation most people will be used to the status quo whether it's better or worse. It will seem like nothing has changed.
