The fear, which many (like myself, and Andrew Yang) have since before GenAI hit it big, is that the coming automation revolution will be magnitudes more disruptive than prior economic revolutions.

Management, warehouses, logistics, driving, retail/service industry, entertainment and advertising, programming/software engineering, even research and education. Potentially tens of millions of jobs in the US alone.
COMBINED with the seemingly zero discussion in mainstream politics about improving the welfare system of the country to prevent system-scale unemployment and poverty, while the profits from "efficiencies" go to the small group of already-wealthy shareholders and owners.
