Deleuze/What Is Philosophy

D&G explicitly call out computer science, marketing, and design as the "shameless rivals" who stole the word "concept" and debased it into product features and data models. They're not being cute — they're saying that when you call your JSON schema a "concept," you've replaced creation with representation, and philosophy has to fight back by making concepts that are "aerolites rather than commercial products."

The event vs. the state. D&G say a concept "extracts a pure event from things." This is strange language, but it means: a concept doesn't capture a state of affairs or a transition between states — it captures the becoming that makes states possible at all. Computational abstractions are fundamentally about states and well-defined transitions. Even monadic sequencing is about chaining state transforms. Philosophy is trying to get at something prior to that level.
