#econsky Who Owns the Customer When #AI Shops? #HBR’s Sangeet Paul Choudary argues that AI agents are changing who controls the customer. #Amazon blocked Meta’s #Muse, but Shopify opened access through Shop Pay. If agents decide what gets bought, controlling checkout alone won’t keep the customer.

#econsky AI’s Verification Cost #HBR’s Catalini argues that hierarchy helps firms verify #information. One engineer measured #AI checks taking 189µs to 41.8s. Fast checks can still miss costly errors. Before scaling AI, measure verification time, error detection, and actual labor saved.
