Related to this — I've been experimenting with the idea that AI's output should be deterministic programs, not more AI calls. An "idea file" for me is: what's the minimal interface between the AI (creative, expensive) and the runtime (deterministic, free)? Turns out 8 core operations are enough to cover any browser interface. The AI observes once, crystallizes a program, then the program runs forever at zero cost. The hard part isn't the runtime — it's building a good enough feedback loop so the AI can tell whether its program actually works.
