> "...serving ads inevitably leads to an unquenchable thirst for data..." well, to continue playing devil's advocate, we've had hundreds of years of advertising (newspapers, pamphlets, and posters/signs before that) without any kind of systematic data collection, so it's not necessarily an intrinsic characteristic of the advertising business to collect data. in an alternate universe, if banks didn't have such a stodgy and stifling rent-seeking business on the movement of money (transaction fees on everything), microtransactions might be the preferred business model of many online businesses that are now dependent on ads.
