Why does a machine purchase still need human approval, when the machine can pay?

Machine Commerce Conditions MCC-001 · Published

From MCC-001, an essay: a hypothesis, not a measurement.

The short answer

Because paying is not the hard part. The essay argues that automating payment leaves the buying decision exactly where it was, and that spending caps and approved-supplier lists narrow what a machine may do rather than telling it what to buy.

As published in the issue

If the owner must still investigate every purchase, little judgment has been delegated. Lower spending limits and restricted supplier lists manage uncertainty by narrowing what the machine may do. Human approval consumes the attention that delegation was supposed to save.

Why it matters

Delegation is what an owner is actually buying, and approval is what it costs. If the binding constraint is evidence rather than payment rails, the work in front of the sector is measurement rather than plumbing.

What we measured

Nothing here was counted. The essay sets out three tests that would put its argument to a measurement, and the one for this question asks whether richer evidence lets an owner approve fewer purchases at comparable risk; the essay states that none of the three has run.
