AI stopped being a pilot project and became company policy today — Uber just put all 30,000 employees on ChatGPT Work, and the interesting question is no longer whether these agents work, but what 30,000 daily users do to a company. Meanwhile, the infrastructure that trust depends on took a hit: 333 Tor exit nodes were hijacked to intercept SSH traffic, a reminder that decentralization is a promise, not a guarantee, and anything not end-to-end encrypted was fair game. Over in the world of deliberate decentralization, Ethereum researchers drafted a consensus overhaul chasing faster finality and post-quantum signatures — the kind of foundational bet that pays off years from now. Meta, meanwhile, is paying the bill for surveillance advertising in public: since the EU let Europeans choose less-personalized ads, ad revenue has slowed, which means privacy finally has a visible price tag. And the UN has quietly accepted we’ll overshoot 1.5°C, which makes the AI-energy conversation feel less like an option and more like a deadline. Busy Thursday.

• Uber puts all 30,000 employees on ChatGPT Work

  Uber has rolled ChatGPT Work out to its entire 30,000-person workforce after an earlier, much smaller pilot, making one of the largest corporate AI deployments a company-wide default overnight. The move marks enterprise AI’s shift from cautious experimentation to mandatory infrastructure — and with 30,000 daily users, it will stress-test what these agents actually do to productivity rather than what they promise in a slide deck.
• 333 Tor exit nodes hijacked to intercept SSH traffic and retrieve plaintext email

  Attackers hijacked 333 Tor exit nodes and used them to intercept SSH traffic and scoop up plaintext email over a three-day stretch this month, in what reads like a dragnet for credentials and sensitive data. The episode is a cold reminder that Tor’s exits are volunteer-run choke points — whoever controls enough of them can watch everything that isn’t wrapped in end-to-end encryption.
• Ethereum Researchers Draft a Consensus Overhaul for Faster Finality

  Ethereum researchers have drafted a consensus overhaul that would split validator voting in two, targeting faster transaction finality, a sturdier fork-choice rule, and a long-term path to post-quantum signatures. If it ships, this would be the most significant change to how Ethereum agrees on its state since the Merge — and the post-quantum thread ties straight into the parallel effort to make Bitcoin quantum-ready before it’s too late.
• UN says we’re going to blow past 1.5º warming, offers a “now what?” answer
  Source: Ars Technica
  
  The United Nations now accepts that the world will blow past 1.5°C of warming, with the best available case being an overshoot to 1.8°C accompanied by massive carbon removal. The ‘now what?’ answer — overshoot first, clean up later — puts the carbon ledger up against AI’s exploding compute appetite, and neither side of that equation is shrinking, which should make the datacenter energy conversation a lot more honest.
• Meta’s Ad Sales Are Suffering Now That Europeans Can Pick Less Personalization

  Meta’s ad revenue has slowed since the European Union introduced its Less-Personalized Ads model at the beginning of this year, according to the company’s own earnings briefing. When users get a genuine choice, a meaningful share of them pick privacy — which means the surveillance-advertising business model now carries a visible, measurable price tag, and Meta is paying it in public.
• Architecting Governed, Self-Evolving AI Agents on Gemini Agent Platform
  Source: Google Dev General
  
  Project Chrysalis pairs Google Cloud’s Gemini Enterprise Agent Platform with its Agent Development Kit and BigQuery behind a four-gate, defense-in-depth security model, aiming at agents that govern themselves and improve over time. The interesting bet here is the governance layer — as agents gain autonomy, Google is selling the seatbelts as a first-class product rather than an afterthought, which is exactly where enterprise buyers’ anxiety lives.

📚 Principal Triangulation of Great Britain
The Principal Triangulation of Britain was the first high-precision triangulation survey of the whole of Great Britain and Ireland, carried out between 1791 and 1853 under the auspices of the Board of Ordnance. The aim of the survey was to establish precise geographical coordinates of almost 300 significant landmarks which could be used as the fixed points of local topographic surveys from which maps could be drawn. In addition there was a purely scientific aim in providing precise data for geodetic calculations such as the determination of the length of meridian arcs and the figure of the Earth. Such a survey had been proposed by William Roy (1726–1790) on his completion of the Anglo-French Survey but it was only after his death that the Board of Ordnance initiated the trigonometric survey, motivated by military considerations in a time of a threatened French invasion. Most of the work was carried out under the direction of Isaac Dalby, William Mudge and Thomas Frederick Colby, but the final synthesis and report (1858) was the work of Alexander Ross Clarke. The survey stood the test of time for a century, until the Retriangulation of Great Britain between 1935 and 1962.
