Its scary because it replaces the thinking jobs, which are the well-paying ones. It hits home to folks who have been lucky to survive the previous societal purges of employment.
All jobs are thinking jobs, with varying degrees of physical effort. E.g. From A senator/congressman have to physically present in senate/congress, to argue/vote their case/bill (which comes from feedback from their followers, requires physical interaction) to bricklaying/road building/whatever you can imagine to lowest level. Some require more thinking and some less.
Impact seems unimaginable. May be we need an AI to AI all imaginable/unimaginable scenarios.
Honestly a congressperson seems easiest to replace with AI from your description. They have an absolutely tiny amount of physical presence with their voters... a burger flipper has far more.
Then you're completely missing the point on road building... This job is already super highly automated. 2000 years ago it took a Roman division to build a mile of road. Now it's just a few people and a lot of equipment that is getting more and more automated every year.
