The article speaks more about the "knowledge workers", the CC Baxters of the world performing more or less bullshit jobs [1]. The 2-3 billion unemployables of the next 10-20 years are not knowledge workers and will all be replaced forever by embedded robotics with good enough networks and statistical learning for following given goals while generating sub-goals.

Boston Dynamics' Spot costs $75K today and Atlas is around $150K, once the price gets closer to $10K there is very little reason to ever employ persons as assembly line workers, construction workers, warehouse workers, machine operators, truck drivers, janitors and cleaners, agricultural workers, security guards, food service workers, garbage collectors, and so on.

And even if 3 billion people could be forced to do spreadsheets to "earn" a living, "by the sweat of [their] brow", that would be an even sadder world than our currently sad world.

My argument is that we need a new metaphysics for what work and life means, one where the right of a person to have food and shelter is not tied to the economic value they produce. But I have no hope for this world: the trillionaires of tomorrow will share even less than the billionaires of today.
