The Intelligence Economy

At Cannes, OpenAI declared the shift from the attention economy to the intelligence economy — and put a rate card on the answer. Six months of verified record tell a stranger story: the product is a familiar sponsored card, the price fell as the pitch rose, the minimums collapsed from $200K to zero, and every trust metric is self-reported with no referee. Meanwhile the ecosystem split seven ways on the same question: OpenAI all-in, Microsoft selling quietly, Google hedges by surface, Meta monetizes around the assistant, Grok announces, Perplexity exited over trust, and Anthropic bought Super Bowl airtime to refuse. These aren't seven marketing strategies. They're seven objective functions — and the forecast gap between OpenAI's $2.5 billion and the category's sub-$1 billion is where the argument gets settled.

The most trusted surface in software is selling adjacency to its own credibility, and the referee’s chair is empty.

  1. Season 2's second poll asked what becomes the new shelf space once agents decide what gets considered, and 16 ballots produced a tie: Retrieval results and Paid recommendations at 31% each, Training data and Default integrations at 18%. Sixteen votes was the smallest turnout of the run to that point and settles nothing, but the grouping is worth a paragraph — the room picked the two routes into a consideration set that an operator can change inside a planning cycle without anyone else's approval. The Restock Test sorts all four by how long a change takes to land and whose approval it needs. My vote went to paid recommendations, for one reason: it's the only one of the four with a price, and a price drags an owner, an auction, and a contract along behind it.

  2. I rebuilt the retrieval system behind Ask Evgeny in one day: traces on every query, a 975-node knowledge graph, authority buckets on every position, and three model upgrades running in shadow. The most important thing that shipped is the feature that measured itself and refused to launch.

  3. The Season 1 finale. Eight Friday polls were one question asked eight ways — who issues the credential that lets an agent act? — and the room's own ballots supply eight structural constraints on the answer. Run the three candidates against all eight and only one survives: protocols carry the credential, constitutions bound it, contracts create it. The issuing layer is an Answerer of Record — the agentic successor to adtech's seller-of-record — because trust is conferred, never computed.

  4. A complete build recipe for putting a grounded answer engine on top of your own writing: chunk the corpus, embed it, retrieve with a multi-lane hybrid, generate with hard grounding rules, track when your own positions change so the system never quotes a retracted stance as current, and expose it two ways — as an MCP connector any chat client can use, and as a chat box on your own site. Every part runs on one Cloudflare Worker for near-nothing. The honest version: the architecture, the guardrails that keep it from lying, the four bugs that actually cost me an afternoon, and the loop that makes it smarter every time you publish.

  5. Before any CMO deployed an agent, a billion customers did. The click did not die of natural causes — the answer layer intercepted intent, then started selling media against it. And a whole measurement industry formed before anyone validated the metric.

  1. Dense numerical representations as the post-ID connective tissue — lookalikes, contextual targeting, cross-media without identifiers.

  1. When AI delivers answers directly instead of links, SEO becomes about AI comprehension — not keyword density. Eight strategic shifts marketers must make as the SERP gives way to the response.

    Who Does the Shopping?

    From mobile and social discovery to AI-assisted and delegated buying

    3 essays on this path

    Which shopping tasks have moved to software, under whose authority, and with what verifiable value for merchants. Twelve buying routes across ChatGPT, Google, Microsoft Copilot, Perplexity, Amazon, Walmart, TikTok and Meta; the ACP, UCP and AP2 specifications read at pinned commits; a sandbox study of an AI agent shopping a test store; and a merchant contribution worksheet with displacement. Assistance is widespread, approval-based checkout is documented in a few assistants, and documented delegation is narrow and platform-bound.
