Jevons Paradox

When technology makes a resource cheaper, total consumption rises — applied to cognition and labor to argue AI produces more work and more engineers, not fewer.

Also known as: Jevons paradox, Jevons' Paradox, Jevons paradox (Wardley's reading), Jevons paradox (on cognition), demand elasticity, unhobbling

Jevons paradox (Wardley's reading)Explicitly NOT just price elasticity or unmet demand. The real engine is 'adjacent possibles becoming real and expanding' — once a capability is cheap and ubiquitous, entirely new industries become buildable on top of it (componentisation effects).

Jevons' ParadoxWhen technology makes a resource (here: labor in a task) cheaper to use, total consumption of that resource increases because new demand is unlocked — applied to AI automation of jobs

demand elasticityThe degree to which reducing the cost of a task via AI creates new demand for that task and adjacent tasks, rather than simply eliminating jobs

Jevons paradoxBorrowed from economics: efficiency gains in AI inference lower per-unit cost, which expands viable use cases and therefore increases total energy demand rather than decreasing it.

Jevons paradox (on cognition)Shoup's central forecast device. Original (1850s–1860s, William Stanley Jevons): when coal extraction became 10x cheaper, net spending on coal rose, because at the lower price entirely new uses became economically viable. Shoup's application: cognition is now near-free; therefore tasks that were not economically viable as cognitive work will now be done, and the number of engineers (and jobs) will rise, not fall. He pairs it explicitly with the 1900-agriculture analogy to argue that catastrophic-sounding workforce shifts can be true at the surface and benign-to-positive in long-run aggregate.

Jevons paradoxMaking code cheaper to produce (via automation, now coding agents) does not reduce total engineering demand — it increases it, because falling cost drives rising consumption of software.
