Product design exists in the real world (outside our head). We have places we need cabs for, groceries which need delivery, and music we want to listen to.

Companies, and tools seek (needs, attention) and work with those externalities – mostly trading off needs, and value by reading our actions.

As tool–making is shapeshifting what does design for agency (design for the world inside my head) look like?

Plotting ideas on the scale of universality (plug and play, or completely unique, including steps in–between) could be a good place to start.
