Play is one. Labor is so tied to functionality, whereas play is a category of non-functionality.
Play captures a lot of what goes on in the world. There is a kind of raw opportunism in biology and chemistry, where things work stochastically to form emergent systematicities. It’s not a matter of direct functionality. We need to develop practices for thinking about those forms of activity that are not caught by functionality, those which propose the possible-but-not-yet, or that which is not-yet but still open.
