The Week the System Incriminated Itself
Some weeks you don't have to investigate anything. The case file opens itself. Corporations publish their own confession in the fine print, courts pile up eight hundred and fifty sanctions against lawyers who let a machine fabricate their case law, and in Colorado a network of cameras calculates your average speed and mails you the ticket without a single human witness. This was one of those weeks.
Microsoft has at least seventy-five products named Copilot. Apps, features, platforms, a laptop category, a tool for building more Copilots, and a physical keyboard key — the first new key on a Windows keyboard in almost thirty years, announced January 4, 2024 — to summon it all. Tey Bannerman took the trouble of counting them on March 31, 2026. But this week someone else took the trouble of reading the terms of service. "Copilot is for entertainment purposes only," says the disclaimer, last updated October 24, 2025. "Don't rely on Copilot for important advice. Use Copilot at your own risk." Seventy-five products. One disclaimer. And a button on the keyboard to invoke them all. In Mexico City's Doctores neighborhood they call this fraud. In Redmond they call it Terms of Use.
Eight hundred and fifty-four. That is the number Damien Charlotin maintains in his judicial hallucination database: sanctions against American attorneys who filed briefs with citations fabricated by artificial intelligence. The foundational case was Mata v. Avianca, June 2023, Southern District of New York. Attorney Steven Schwartz asked ChatGPT for case law and ChatGPT invented six cases that never existed. Judge P. Kevin Castel sanctioned Schwartz and his colleague Peter LoDuca. Since then the figures have become routine: in March 2026, the Sixth Circuit hit attorneys Van R. Irion and Russ Egli with fifteen thousand dollars each, plus full opposing counsel fees, plus double costs. In Oregon, a federal court ordered payment of one hundred and nine thousand seven hundred dollars — possibly the record. The legal standard is clear: Rule 11 obligations are non-delegable. The attorney's signature certifies the citations exist. The machine is not at fault. Whoever signed is.
Julius Brussee is sixteen years old, studies at Leiden, and this week published a GitHub repository that cuts Claude Code token consumption by seventy-three percent. The method: force the AI to talk like a caveman. No articles. No pleasantries. No "I'd be happy to help." From sixty-nine tokens to nineteen. Technical accuracy stays intact — the code doesn't change, only the fluff disappears. Seven hundred and seven GitHub stars in twenty-four hours. "Why use many token when few token do trick," says the README. So the most efficient optimization of the year is linguistic regression. You couldn't make this up.
In Colorado, punishment no longer requires witnesses. Law SB 23-172 authorized Automated Vehicle Identification Systems: cameras that photograph your vehicle at one point, photograph it again miles later, divide the distance by the elapsed time, and if the average exceeds the limit by ten miles per hour a seventy-five-dollar fine arrives by mail. No license points. No police present. Eight cameras covering both directions of I-25 between Mead and Berthoud across six miles. The rollout began in July 2025 on Highway 119 between Boulder and Longmont, where speeding violations dropped over eighty percent. On I-25, during the warning period that ended April 2, 2026, excessive speeding dropped ninety percent. CDOT Chief Engineer Keith Stefanik said the goal is not to punish drivers but to prevent crashes. Waze won't save you — the cameras rotate positions. Braking to sixty-five for the cameras and hammering back to eighty-five doesn't work: the system measures the average, not the instant. Surveillance no longer needs eyes. Just arithmetic.
Pankaj Gupta holds a Ph.D. from Stanford and was a senior ML manager at Twitter. Gilad Mishne was his colleague there in 2010. Together they founded Yupp in June 2024 with a reasonable idea: free access to over eight hundred AI models, users evaluate which responds best, and Yupp sells that preference data to the labs. Chris Dixon at a16z crypto led the thirty-three-million-dollar seed round. Jeff Dean from Google DeepMind invested. Biz Stone, Twitter co-founder, invested. Aravind Srinivas from Perplexity invested. Forty-five more angels invested. One point three million users signed up. The VIBE Score leaderboard ranked models by human feedback. It all sounded right. On Tuesday, March 31, 2026, Yupp announced it was shutting down. Less than a year. "The AI model capability landscape has changed dramatically in the last year alone," Gupta wrote on X. The market moved faster than the product. In Mexico City's Tepito market they have another name for this. They call it burning the cash.
