Building the infrastructure for a future world where the things you can do are discovered via a negotiated system of API brokerages and human-friendly front ends is very cool and very scifi — a kind of taxonomy of potential action.
But taxonomy (hat-tip @redsesame) is frozen opinion, not objective truth. Building a world where people know what they can do via systems of discovery constrains as much as it enables; it pushes what is not describable, monetizable, or desirable to the margins.
