AI is going to outright replace a whole bunch of what are currently decently paying, stable, office jobs: accountants, clerks, schedulers.... and AI-augmentation is going to allow 1 person to do the same work that currently requires 2+ in so many fields.
Law and Medicine, two fields that have historically been good pathways to the middle class, are likely going to see AI hit them first in the middle, with the need for non-senior/non-specialized doctors/lawyers dramatically reduced as AI-assisted tools become standard.
As the middle gets cut out, more people are pushed towards lower-skill jobs that require physical interaction, likely pushing down wages in a buyer's market and decreasing the incentives for robotic automation.
That's going to be a massive blow to the US and global economy, all without having to build a single robot.
