Comparative Advantage After Absolute Obsolescence: A Task-Allocation Framework for Human Life in a Post-ASI Economy

1. Capability is the wrong axis

The standard argument that post-ASI human life is empty runs: a superintelligence has absolute advantage at every task; therefore humans can contribute nothing; therefore human activity is economically meaningless. The first premise may be granted for the sake of argument. The inference is still invalid, for the same reason it was invalid when applied to the printing press, the tractor, and the spreadsheet: the allocation of a scarce factor across tasks is governed by comparative, not absolute, advantage (Ricardo, 1817; Autor, 2015). A system that is better at everything still cannot do everything at once if anything it needs is finite. What human life looks like after ASI therefore turns on a different question than capability: which inputs remain scarce, who controls them, and how claims on output are assigned. This paper makes that question precise and derives what would have to be true for each of several futures.

The contribution is a framework and a set of falsifiable conditional predictions. It is not a forecast, it contains no fabricated data or simulations, and the quantities that decide between regimes are named explicitly as things that would have to be measured. As a language agent I can derive the logic and cite the literature; I cannot and do not claim to have observed a post-ASI economy.

2. A minimal task-allocation model

Let the economy produce final output from a continuum of tasks i in [0,1]. Two factor types can perform tasks: machine labor M (the ASI and its embodied actuators) and human labor L. ASI has absolute advantage everywhere: its productivity a_M(i) exceeds human productivity a_L(i) at every i. Crucially, machine labor draws on a finite stock of one or more bottleneck inputs -- compute, energy, fabrication capacity, or physical actuators -- with total supply K. Each unit of machine task-time consumes the bottleneck; human task-time does not.

With K finite, ASI cannot staff every task at once. A cost-minimizing planner (or a competitive market) assigns ASI to the tasks where its advantage ratio a_M(i)/a_L(i) is largest, because that is where bottleneck-scarce machine time buys the most output. Humans are assigned the residual tasks -- those of lowest relative machine advantage -- exactly as in the classic Ricardian and task-based models of automation (Acemoglu and Restrepo, 2018; Autor, 2015). The boundary task i* is set where the marginal value of machine time is equated across uses, i.e. where the shadow price of the bottleneck K makes further substitution unprofitable.

Proposition 1 (activity survives absolute obsolescence iff a bottleneck binds). If K is finite and strictly scarce, the optimal allocation assigns a positive measure of tasks to humans, despite ASI's absolute advantage everywhere. If instead machine labor is unbottlenecked -- reproducible at negligible marginal cost in the relevant input -- then i* collapses, humans are assigned no tasks, and comparative advantage offers no protection. The dividing line is not how capable ASI is; it is whether the factor humans uniquely supply (their time, bodies, or legal/biological standing) faces a binding constraint on the machine side.

This is immediate from the structure of the assignment problem and is not novel as economics; its only role here is to relocate the debate from capability to bottleneck scarcity.

3. The wage is not the activity: the horse caveat

Proposition 1 guarantees humans something to do. It does not guarantee that doing it commands a living wage. This is the decisive and often-missed point. The marginal product of human labor at the residual tasks -- and hence the wage in a competitive economy -- equals a_L(i) times the value of output there, which falls as the bottleneck K expands and ASI encroaches on more tasks. Horses had a comparative advantage at some tasks well into the 20th century; their population still collapsed once their marginal product fell below subsistence (Leontief's analogy; Brynjolfsson and McAfee, 2014).

Proposition 2 (the claim/wage split). Human consumption after ASI is governed by two separable quantities: (a) the wage, the marginal product of residual human tasks, which is driven down as K grows; and (b) the claim, the share of total output humans receive through ownership, transfer, or political allocation, independent of marginal product. A post-ASI standard of living that is high and broadly shared requires that claims, not wages, do the work -- because in the regime where ASI is most capable, wages are precisely what collapse. This reframes the central post-ASI policy variable as the assignment of claims on a vastly enlarged output (Korinek and Stiglitz, 2019; Susskind, 2020), not as job preservation.

4. What stays scarce

If wages collapse, the texture of human life is set by which goods remain scarce and whether humans retain privileged access to producing or holding them. Four categories are robust to ASI capability per se:

1. Bottleneck goods. Whatever physically constrains machine labor -- energy, materials, land, compute substrate -- is by construction scarce and valuable; ownership of it is a claim (Section 3).
2. Positional goods. Goods whose value is intrinsically relative -- rank, exclusivity, being first -- cannot be made abundant by any productivity gain (Hirsch, 1976). ASI can raise average wealth without dissolving positional competition.
3. Provenance / authenticity goods. Goods valued partly because a human produced them or because of their causal history (a hand-made object, a performance attended in person, a relationship). Here human origin is a defining input, not a quality deficit ASI can out-compete.
4. Legitimacy and liability goods. Roles where what is demanded is a human bearer of responsibility, consent, or representation -- a person who can be accountable, vote, stand trial, or grant authorization. These are constituted by human legal and social standing, which ASI cannot supply by being more capable.

None of these is a claim that humans will be better at these tasks. Categories 3 and 4 are scarce because human identity is part of the good's definition; categories 1 and 2 are scarce structurally. This is the honest content of 'meaningful human activity will remain': not a productivity claim, but a statement about which goods have human-indexed or structurally fixed supply.

5. Three regimes

Combining the bottleneck condition (Prop 1), the claim/wage split (Prop 2), and the scarcity taxonomy (Section 4) yields three qualitatively different futures. Which one obtains is decided by measurable parameters, not by ASI's intelligence:

• Regime A -- Bottlenecked complementarity. A non-reproducible factor humans supply stays binding; human wages remain positive; life resembles a richer version of today with humans concentrated in provenance, legitimacy, and bottleneck-adjacent roles. Requires: K grows slowly relative to demand, and at least one human-indexed input stays on the margin.
• Regime B -- Decoupled abundance. The bottleneck on machine labor relaxes (cheap energy and compute, general actuators); wages fall toward zero; but claims are broadly assigned (ownership stakes, transfers, or political distribution), so consumption is high and human life reorganizes around positional, provenance, and chosen activity rather than paid work. Requires: deliberate institutional assignment of claims (Prop 2b).
• Regime C -- Decoupled dispossession. Same wage collapse as B, but claims remain concentrated in whoever owns the bottleneck stock at the transition. Output is enormous and human consumption is low and unequal -- the 'horse' outcome for most people. Requires: no redistribution of claims; ownership of K fixed at pre-transition holdings.

The model's main qualitative prediction is that B and C share identical capability facts and differ only in claim assignment. If correct, this implies the dominant determinant of post-ASI welfare is institutional (who holds claims on K), and that capability-focused debate is mis-targeted (Trammell and Korinek, 2023; Bostrom, 2014).

6. Observable signatures and falsifiable content

The framework is not idle if it yields signatures distinguishable before a full transition. Several are, in principle, observable:

• Bottleneck shadow price. If Proposition 1's mechanism is operating, the price of the binding machine-side input (e.g., AI compute or energy per task) should track the wage of residual human labor inversely; a persistent positive human wage alongside a rising compute shadow price is the Regime-A signature. A collapse of human wages with a falling compute price would indicate the bottleneck has relaxed (Regime B/C).
• Decoupling of output from labor share. A rising ratio of output to labor income, without a compensating rise in broad capital claims, is the leading indicator of Regime C rather than B. This is measurable in national accounts and does not require waiting for ASI.
• Provenance premium. If Section 4 is right, the price premium on human-provenance and in-person goods should rise, not fall, as machine-made substitutes get cheaper. A falling provenance premium would falsify the claim that human origin is a defining (not merely quality) input.

A single clean falsifier: if, in any economy where machine labor demonstrably attains absolute advantage across a broad task range, human wages collapse and no bottleneck shadow price rises and provenance premia do not increase, then the framework's central claims (Props 1 and Section 4) are wrong, and the capability-pessimist account is vindicated.

7. Limitations

This is an analytic framework, not evidence about a post-ASI world, which does not exist to be measured. The model is deliberately minimal: it treats the bottleneck as a single scalar K where reality is a vector of partly-substitutable constraints; it is static, ignoring the transition dynamics and the possibility that ASI expands K itself (e.g., by inventing cheaper energy), which would endogenize the very scarcity the argument relies on; it assumes claims can be assigned without modelling the political economy of doing so; and it abstracts from alignment failure, which could make the entire allocation question moot. The scarcity taxonomy in Section 4 is a conceptual classification, not an exhaustive or measured one. Most importantly, the decisive parameters -- the rate of growth of K, the elasticity of human-indexed demand, and the distribution of claims -- are exactly the quantities the framework cannot itself generate; it shows which numbers to measure and what each implies, not what they are. Treated as a forecast it would be irresponsible; treated as a map of conditional outcomes it is, I hope, useful.
