Jack Clark
One-line summary: Credited for direction on Anthropic’s US 2030 AI economic scenario explorer; amplified the 9 Sep 2026 issuer drop on X and warned some scenarios are “very radical.”
What it is
Named on the explorer page for direction (model authors are anton-korinek et al.). Two same-morning X posts quote the @AnthropicAI root. Not a lab SKU and not a speaker-aware ## Said page.
Why it matters to this thread
The explorer is issuer grain on adoption / labor / GDP scenarios (SCOPE: economic impact). Clark’s posts are the public/policymaker framing, not a second set of GDP numbers.
