The Private Capture of Public Genius

公共智慧被私人捕获:AI时代的数据税与群智回归

This essay uses the 1956 AT&T antitrust consent decree—which forced the company to license its entire patent portfolio royalty-free—as a historical mirror to frame how frontier AI labs (OpenAI, Anthropic) scrape the public internet to build private models. The author argues the training corpus is a deltaic accumulation of humanity's collective expression, and compressing it into model weights constitutes a private capture of public genius. It reviews the legal landscape: the Bartz v. Anthropic and Kadrey v. Meta rulings found LLM training 'transformative' under fair use, but the market dilution question remains unresolved. The author proposes a 'Corpus Royalty'—a fixed percentage of gross revenue paid into a public fund distributed equally to every eligible American—as the only administrable remedy for unattributable collective contribution (since Shapley values are computationally infeasible at frontier scale). The piece also explores how different layers of the internet (content, discovery, attention, contribution, integrity) interact and risk collapse under AI-generated spam, and notes that Elinor Ostrom's eight conditions for governing commons are entirely unmet by today's web. Suitable for engineers and researchers interested in AI governance, data policy, intellectual property, and the social contract underlying model training.

Agentic test processes: from chip design to AI workflows

智能体编码中的测试哲学:从芯片设计到AI工作流

Drawing from his experience at chip company Centaur, the author compares test processes that scale well with LLM agents: no code review by default, heavy reliance on fuzzing, and a dedicated test team. He argues that while LLMs are poor at writing tests directly, directed fuzzing with LLMs can find real bugs in minutes. The article highlights the high variance of LLM outputs—benchmark rankings often flip with minor task changes—and cautions against over-reliance on aggregated metrics. Through examples like building a superhuman board game AI, he advocates systematic data-driven iteration over prompt tricks. Targeted at engineers interested in AI-assisted development, testing, and agent workflows.

Agentic test processes, LLM benchmarks, and other notes on agentic coding from Galapagos Island

Agent 编码的测试、基准与方差:来自一线的深度复盘

Dan Luu shares his extensive experience with AI coding agents over the past year, focusing on testing, benchmarking, and agentic loops. He compares fuzzing vs. LLM-driven bug finding, finding fuzzing faster with lower false-positives; evaluates 'caveman mode' with 50 runs showing inconsistent savings; highlights high variance in LLM benchmarks, making public evals nearly useless for individual users. He also discusses automated PR generation from support tickets, multi-persona false-positive reduction, and challenges in data analysis and autonomous loops. For engineers interested in real-world effectiveness of AI coding tools.
