Jevons Paradox
Efficiency can increase total consumption.
If
Making a resource cheaper to use per unit lowers its effective price and can raise total consumption instead of lowering it — the efficiency gain is spent on more usage rather than banked as savings.
Then
When you make something cheaper — compute, storage, an internal API — expect demand to balloon; provision and budget for the rebound instead of assuming a net reduction.
Unless
Cap the Rebound — pair efficiency with a quota, cap, or price signal to actually capture the savings
