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.

The sentence above is quoted from the essay as published and is not re-written here. The essay, its date and the address it was published at are below.

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 that matters is measurement rather than plumbing.
