>What problems do Chu spaces allow me to solve Based on this article, Chu spaces feel like a representation of a state space, and exploring limits to the relationships between state spaces while keeping certain invariants. I'm not sure how high up the abstraction pile this thing sits, but it seems pretty high. That implies that a "practical" application is going to be hard to motivate because you're talking about invariants not of your tools, or even of the tools someone used to make your tools, but the tools someone else used to make those. (This is the general problem with category theory: everyone wants to out-meta each other so badly they don't notice when the discussion gets so rarefied that most everyone has already passed out.)
