The corpus contains a genuine, unresolved contradiction about whether brand equity helps or hurts in the AI era — worth holding explicitly.

- **Furr/Shipilov (liability view)**: brand equity on factory-identical goods is a *liability*, a reason to be bypassed once agents expose equivalence ([[contrarian-brand-equity-liability]], [[claim-generic-brand-premiums-will-collapse]], [[claim-objective-factors-over-brand-loyalty]], [[concept-generic-brand-penalty]]).
- **Greeven (asset view)**: brand marketing *remains essential* because equity gets hardcoded into prompts — 'Order burgers from McDonald's, not any burger' ([[claim-brand-marketing-remains-essential]]).
- **Gale (transformed view)**: symbolic master brands (Disney, Starbucks) *fail to appear*, surfacing only via attribute-rich sub-units ([[claim-sub-units-over-master-brands]], [[question-legacy-lifestyle-brands]]); storytelling is only indirectly useful ([[contrarian-storytelling-ineffective]]).

**The reconciliation the corpus supports**: brand is now *one data signal* the agent weighs, not an automatic moat. Equity **unbacked by measurable differentiation** is the liability (commodity categories, rich reviews); equity that *shapes the user's prompt* or is backed by attributes/evidence remains a powerful asset — connecting to [[cross-day-prompt-as-mandate]] and [[cross-day-defensible-moats]]. In high-stakes categories (health, finance, B2B), trusted brands may even be *privileged*.
