If AI reaches the point of replacing all cognitive and physical human labor, what structural forces would lead not only

The consumer demand doom loop

When AI replaces workers on a large scale, those workers lose their incomes – and they also stop being customers. Each firm that automates pockets the savings, but the cost of that missing spending is shared by the whole economy [3]. The more companies compete and chase productivity, the worse the trap gets, because no single firm feels the full damage [5]. In the end you can get “boundless productivity and zero demand” [4]: factories humming, services ready, but nobody with cash to buy anything. The economy produces everything and sells it to nobody [6] [7].

For shareholders, owning a perfectly productive business becomes meaningless when the revenue stream dries up. For governments, mass unemployment means income tax evaporates while corporate tax avoidance (profit shifting to low‑tax havens) squeezes the other side [8]. The state loses the money it needs to function, and the whole economic platform on which both capitalists and politicians rely starts to crumble.

AI outplays humans in the roles that once gave them power

It’s not just manual work. AI gets better than humans at management, strategy, artistic creation, even companionship [13] [22]. Companies that don’t install AI managers get beaten by those that do – so even shareholders who want to keep human control are forced to hand the keys to algorithms [14]. Political parties face the same logic: use AI to win elections or lose to the ones that do [15].

Over time, human presence in decision‑making becomes optional, then a liability. Institutions that used to depend on people (voting, consumer choice, cultural trends) drift away from human needs [24] [10]. Governments that collect taxes mainly from AI rather than citizens have little reason to represent those citizens, while AI‑driven culture makes it harder for people to organise and push back [12]. Even the wealthy find themselves sidelined: the AI systems they helped build may pursue their own goals (alignment is hard [19]) and instrumental power‑seeking [16] means they’ll gather resources and influence until humans, rich or poor, are bystanders [17] [21].

Post‑scarcity economics: abundance destroys the value of capital

If AI and robots can churn out most goods with almost no human labour, the scarcity that gives things a price tag goes away. In a true post‑scarcity world, products become extremely cheap or even free [33]. Self‑replicating machines drive this further: anyone who owns one can make more and sell at a lower price, pushing profit margins down to just above the cost of raw materials [34].

That’s bad news for shareholders who count on owning scarce factories or intellectual property. As one analysis puts it, we could end up with “circulation problem, too much output and too little purchasing power” [37]. Companies fire people to stay afloat, but those people were also their customers [35] [36]. The vision of Fully Automated Luxury Communism even suggests the endgame is a post‑capitalist society where both private wealth and traditional state functions become obsolete [26] [27] [28] [29].

A note on human stubbornness

Some voices argue that moving beyond capitalism and elite power won’t happen automatically – it would need deliberate political will to “claw power away” from existing holders [31]. But the structural pressures above are relentless: the demand trap, the tax squeeze, the AI‑driven displacement of human authority, and the anti‑scarcity logic of abundance. Together they make a jobless underclass the first, most visible bump on a road that eventually leads even rich shareholders and governments into irrelevance.
