The @zeit.de has 3 pages on one of our PolPop articles, led by @jacklucas.bsky.social, where politicians reflect on our finding that they perceive voters differently than voters perceive themselves. Would love to see this more often, where the subjects get a chance to reflect on the findings.

*The AI boom = one of the costliest building sprees in world history

* Past 3 years' commitments are greater than the cost of building the U.S. interstate highway system

* Consumers must spend $800 billion on AI within a few years, to justify investment from 2023-24

www.wsj.com/tech/ai/ai-b...

This week, consultants at Bain & Co. estimated the wave of AI infrastructure spending will require $2 trillion in annual AI revenue by 2030. By comparison, that is more than the combined 2024 revenue of Amazon, Apple, Alphabet, Microsoft, Meta and Nvidia, and more than five times the size of the entire global subscription software market.

Morgan Stanley estimates that last year there was around $45 billion of revenue for AI products. The sector makes money from a combination of subscription fees for chatbots such as ChatGPT and money paid to use these companies’ data centers.

How the tech sector will cover the gap is “the trillion dollar question,” said Mark Moerdler, an analyst at Bernstein.

Our results are especially interesting in the context of collective attention: Whereas books, news stories, movies, etc. get popular, then lose popularity at a higher and higher pace (see www.nature.com/articles/s41...), the most-popular hit songs now stay popular for longer.

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**.

Paper: arxiv.org/pdf/2509.08825

$We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation". We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks. For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations. Then, we collect 13 million LLM annotations across plausible LLM configurations. These annotations feed into 1.4 million regressions testing the hypotheses. For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions. Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors. Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models. Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.$
