We might just keep making more jobs and coming up with more busy work to keep people grinding away for 40 hours a week.

If you look at 1940, women were ~24% of the workforce. Now in 2025 they are ~48%. The numbers are probably similar with immigrant workers having increased greatly in the last 80 years.

If you view AI workers as just more labor flooding the workforce it might have a similar affect. If we flooded the 1940s economy with 10s of millions of qualified women and immigrant laborers people would have viewed it as devastating to the economy, but introduced gradually over time we arrive at a point now where we fear what would happen if they went away.
