Oh I've always thought people like SUVs just because they want a bigger and pricier toy than the other guy. Is it not so?
> isn't just a marketing delusion, but subjective joy
What is the difference? When a product is being marketed, isn't the subjective joy created by the marketing?
Attributing all joy and personal preference people experience to marketing influence is a pretty cynical take, and also a pretty inaccurate and overly simplistic one: Some people might never be reached by a marketing effort, yet buy a specific car because they remember a childhood story, or like pronounced rounded shapes, or because the interior design appeals to their sense of fashion.
Or more specifically, for the case of coding agent harnesses, where many developers have experimented with a wide range of tools - someone might just favour the interactions with a specific one from their personal experience. Entirely unrelated to marketing.
