Britain has a habit it cannot break. We invent the future, then we sell it to people who understand its value better than we do. This week a select committee told ministers to remove Palantir from the NHS, and the company's British boss spent the days that followed defending the contract like the politician he is. In this issue, David Richards MBE asks who really owns the most valuable dataset in the world, and whether we are about to repeat with our health records the mistake we made with DeepMind.

In this episode:

The £10 billion goldmine. Why Palantir hired a Westminster networker rather than an engineer, the holes in Louis Mosley's Telegraph defence, the Nick Clegg parallel, and the National Grid precedent for ripping foreign technology out of critical infrastructure. Plus the close that ties it together: how Britain built DeepMind, sold it to Google for around £400m, and handed Silicon Valley the very capability it feared.

• The 17-year itch. David's Digital Forge conversation with Richard Stubbs of Health Innovation Yorkshire and Humber on why proven NHS technology takes an average of seventeen years to reach patients, why there are "more pilots than British Airways," and the safety question nobody dares ask.

• Would AI have locked us down? David's Yorkshire Post column on the Imperial model, the statistics watchdog's rebuke of the Covid Inquiry, and what AI-assisted models would actually tell a minister to do today.

• The layoff tracker, Week 23: US tech's heaviest month of cuts in nearly two years, and the mechanics of AI laundering.

Whatever you believe about AI, check the date on it. In this field, out of date means days, not years.

This week three things landed together: a Sequoia keynote arguing this is a revolution in computation rather than communication, a Y Combinator chief executive shipping like a team of twenty, and a banking boss caught describing 7,800 job cuts as "replacing lower-value human capital."

David Richards MBE connects them, then turns to the economics (one firm reportedly spent half a billion dollars on Claude in a month) and the human cost recorded in the weekly Sunday Signal Layoff Tracker: 472,150 cuts so far this year, 169,430 of them in tech.

In this episode:

• Why Pat Grady says "the floor keeps moving underfoot"
• Garry Tan, gstack, and one builder shipping like twenty
• The survival playbook for anyone whose job is a task
• The 725 billion dollar capex wager and the dot-com parallel
• Standard Chartered, ClickUp, and the algorithm in Thatcher's coat

The AI energy debate has been built on a single assumption. That hyperscalers will buy raw electricity at any premium because they have no other choice. A British company in Oxford has the receipts to prove that assumption is wrong.

This week, the full interview with Dr Xianxin Guo, CEO of Lumai, the only company in the world running billion-parameter LLMs on optical compute. Ninety per cent less energy. Cost per token that rewrites the economics of inference. And the procurement-not-subsidy demand he is making of the British state.

Plus the layoff tracker hits another 18,800 this week, led by a 170-year-old British bank telling investors it is replacing "lower-value human capital" with AI, the most candid C-suite line of 2026 so far.

Three stories. Photons. Power. Britain.
