Sam Altman: Proof of Human in the Age of AI

Worth hearing: unlike the broader AI forecasts elsewhere in the corpus, this appearance develops a distinctive thesis about proof of personhood, agent commerce, and credential infrastructure. It is plainly promotional, but the adoption figures and $50 billion free-cash-flow scenario add unusually concrete—and debatable—claims.

Oh, yeah. Well, I mean, there are 8 billion people in the world, and you know, about 6 billion of them are online in some form or fashion. You know, something like 4 billion of them have a smartphone. And so the the immediately addressable TAM is the 4 billion people in the world that have access to a smartphone. Um, I think you could see a world where, you know, today it's it's around 20 million users, so it's early days, but we could really see that scale to billions of people over time. And you can see why it'd be valuable for each person, you know, on the order of five, ten bucks a person in value a year is maybe attached to this ID. This could become a$50 billion free cash flow protocol because of how valuable, because of the revenue that it can generate. And that is a very, very valuable system.
