Roundup: Piketty Plan, AI Slowdown, Drones, Borjas Errors
This roundup criticizes Thomas Piketty and the World Inequality Lab’s new global plan—centered on degrowth and a proposed Global Justice Fund—arguing it relies on an outdated RCP8.5 baseline and is politically impractical. The newsletter also highlights data and market signals around generative AI: a chart (via John Burn-Murdoch) using Demirer et al. (2026) suggesting the number of apps with significant usage is falling despite many new releases, and reporting that Sam Altman warned of a meaningful pullback in AI spending. Other items: analysis of modern drone warfare and Western militaries’ slow adaptation, China exporting manufacturing capacity abroad, a paper claiming India’s recent GDP growth may be misestimated, and critiques showing errors in George Borjas’s recent research on immigration and ideology.
Signals about an AI spending pullback and declining app usage affect the app economy, publisher monetization and AI-driven product strategies; Piketty’s high-profile policy proposal is notable but unlikely to be adopted and has limited direct AdTech impact.

Key Takeaways & Evidence Grounding
- Thomas Piketty and the World Inequality Lab published a broad plan emphasizing degrowth and proposing a Global Justice Fund financed via global taxes.
- Piketty et al.’s climate scenarios rely on the RCP8.5 baseline, a scenario many climate scientists now consider implausible.
- John Burn-Murdoch (Financial Times) published a chart, citing Demirer et al. (2026), indicating the number of apps with significant usage is declining even as app releases increase.
- Business Insider reported Sam Altman warning of a significant pullback in AI spending — the first notable pullback since generative AI’s emergence.
- Critics (Katrin Auspurg and Josef Brüderl) identified a coding error and specification issues that, when corrected, render Borjas & Breznau’s reported ideology effect statistically insignificant.

Roundup: AI Model Releases and Societal Impacts
This roundup covers recent technology and policy developments: U.S. "federal debt held by the public" surpassed 100% of GDP for the first time since World War II, with interest payments rising and political consensus to curb debt weak. In AI, Anthropic limited the initial release of its Claude Mythos model amid security concerns, and OpenAI released GPT-5.5, which the UK AI Security Institute rates as comparable to Mythos; commentators warn of AI-enabled cyberattacks but note defenses and AI-assisted vulnerability fixes may blunt harm. The post also reviews evidence that school smartphone bans can modestly improve grades and student receptivity, early‑career hiring and coder employment showed declines after AI releases (papers from Tucker; Crane & Soto), BART fare gates reduced crime and increased revenue, and California YIMBY reforms have helped generate ADUs and other housing units.
AI Roundup: Growth Forecasts, Risks, Privacy, Adoption
A Noahpinion roundup surveys recent AI research, debates, and risks. A Forecasting Research Institute survey finds economists, AI experts, superforecasters, and the public predict similar near-term AI capability gains by 2030, but only AI experts expect a material GDP growth acceleration (up to ~4–5%). The newsletter highlights biosecurity concerns (debate over how easily AI could enable creation of effective bioweapons), accelerating offensive cyber capabilities documented by Lyptus Research, and quantum research that may lower the cost of breaking common cryptography. A paper by Lermen et al. shows LLM methods can deanonymize pseudonymous users at scale. The piece also notes signs of slowing workplace generative-AI adoption in several surveys and raises concerns about widespread, adversarial, or rent-seeking uses of AI (e.g., quant trading, automated hacking).
Exponential View: Agent Era, AI Infrastructure Risks
This Exponential View newsletter reviews major developments around concentrated AI infrastructure, knowledge creation, and the emerging agent era. It reports drone strikes that hit three AWS data centers in Bahrain and the UAE and warns that AI production is highly concentrated — the newsletter cites a Herfindahl‑Hirschman Index of 0.59 for AI chips. U.S. policymakers are debating tiered oversight for large Nvidia clusters (licenses, government assurances for ~100,000‑chip clusters and inspections near ~200,000). The piece surveys debates about AI’s impact on the knowledge commons, examples of AI contributing to research, recent productivity data (U.S. productivity growth of 2.8% Q4‑to‑Q4 2025), and the rise of agentic AI and model releases (noting GPT‑5.4). It also briefly flags reliability limits of AI‑detection tools, de‑anonymization risks, and diverse miscellaneous items from natural history to rare‑disease AI diagnostics.
