In 2014 Britain sold DeepMind for a reported £400 million. Demis Hassabis did not want to sell. His investors had gone cold and the compute he needed did not exist in this country at any price. This May, Anthropic closed a round at a $965 billion post-money valuation.

The government's AI Opportunities Action Plan is a serious attempt to make sure that never happens again, and this episode gives it credit where it is due: public compute has gone from 2 ExaFLOPs to 21 in two years, five AI Growth Zones are designated, and a Sovereign AI Unit has up to £500 million behind it.

The trouble is that it answers a 2014 question, and the question has moved.

This episode goes through where the arithmetic breaks, why Lumai's optical inference launch is real but is not a grid bypass, and what Britain has actually been paid for its health data, using published trust accounts. Milton Keynes University Hospital received consideration worth roughly £3.90 per patient record, once shares, IT investment and an undisclosed royalty are counted. EY's indicative market values put a typical health record below £100.

Plus the Tech and AI Layoff Tracker, the moment Oracle attributed job cuts to AI in a filing, and my Yorkshire Post column on how China built AI at a fraction of the cost of the United States.

Amazon Web Services cannot build enough capacity to meet the demand it already has. Most of 2027 is reserved. Substantial reservations now extend into 2028.

This week: what Andy Jassy actually said on 30 July, and the three things the coverage has got wrong about it, including a demand signal that is more commercially entangled than it looks. Britain's grid connection queue, where data centres account for at least 80GW of proposed demand against 2.4GW connected and a 45GW national peak. Why China's position is weaker than the capacity figures suggest, and what its selective reopening of access to American chips tells you.

Then the question that follows from all of it. If renting compute has stopped being automatic, when does owning it make sense? Real numbers on Nvidia DGX pricing, the AI Enterprise licence that most business cases miss, the 75% Inception discount, and why utilisation and pooling matter more than any crossover figure you have been quoted.

Plus Lumai, the Oxford optical computing company that thinks the answer is needing less power rather than finding more. My Yorkshire Post column on where AI will eventually live. And the layoff tracker: 2026 has passed last year's full-year total with four months to spare, and the companies doing the cutting are profitable.

In 2013 a group of Berkeley researchers sat in my office in Silicon Valley asking for funding for an academic project called Spark. They were not on my calendar by accident. They were there because Konstantin Boudnik, one of the early developers of Apache Hadoop and co-creator of Apache Bigtop, who ran R&D for me, insisted I meet them. A man whose work was closely bound up with Hadoop, telling his chief executive to look hard at the technology most likely to displace part of it. On Thursday that company closed a $5 billion round at a $190 billion valuation.

This episode is the story of what happened in between, and it begins with a second-hand Commodore 64 with a broken tape deck in a Swedish suburb. Four years of nobody wanting the technology. One sorting benchmark that reversed the industry's opinion overnight. A board telling them they had less revenue than the local restaurants. And a set of founders who genuinely did not know how venture capital worked.

Then the claim that got Ali Ghodsi more attention this week than the money did: that artificial general intelligence has already arrived, measured against the definition researchers used before 2022, and that the industry quietly moved the goalposts rather than admit the bar had been cleared. His argument is that AI does not have an intelligence problem, it has a context problem. Demis Hassabis at Google DeepMind says 2029. Greg Brockman at OpenAI will not pick a date. I argue they are answering different questions, and only one of those has already been settled.

Then what AGI actually means once you strip the science fiction out of it: not robots, but a fall in the price of cognition, and the ability to buy thinking without putting another person on the payroll. Goldman Sachs Research on 300 million exposed jobs, why its 16,000-a-month figure is a drag on hiring rather than a redundancy count, and the mechanism that matters more than the attribution, which is a hiring freeze at the entrance.

Then my Yorkshire Post column this week. An AI law firm at Yorkshire AI Labs applied for professional indemnity cover, and the underwriters asked every question about people. We assumed they wanted a human in charge. They were confirming the opposite. The quote came back 50% lower.

And finally the Week 33 layoff tracker update, led by Oracle, which reported headcount down 21,000 in a single fiscal year while spending $55.7 billion on capital expenditure, and told regulators in writing that AI deployment contributed to workforce reductions.

On 16 July a Beijing lab most British executives had never heard of released an open-weight AI model that joined the leading proprietary systems. Eleven days later it published the weights. Within a fortnight the White House had accused the company of stealing American intellectual property and more than 270 technology companies had signed a letter telling Washington to calm down.

In Issue #66, David Richards MBE explains what actually happened, and why it matters far beyond China.

Inside this episode: a plain-English explanation of Mixture-of-Experts, the architecture that let Chinese labs turn a compute constraint into an engineering advantage. What falling model prices do to nearly $2 trillion of American AI valuation, with OpenAI and Anthropic both filed confidentially for public listings. Where Britain really stands, including the two numbers about British AI that nobody puts on the slide. The story of Tommy Flowers, who built the world's first programmable computer and was ordered to burn the drawings. And the Week 31 layoff tracker, where the headline number falls, the tech number rises, and AI is the leading stated reason for the fifth month running.

Every figure is sourced. Anything that could not be verified did not run.

A history professor in Mississippi buried one instruction inside an exam question, in white text, invisible on the page. Put the word Madagascar somewhere in the answer, it said, in a way that makes no sense. Thirty-two of his thirty-five students handed it straight back to him.

The cheating is the obvious story. It is also the least interesting one, because the trap only worked on an assignment a machine could already do end to end.

In this issue: what happened in that classroom, and the Brown University exam that collapsed from 96% to 48.6% the moment it moved into a room. The long history of tools we called cheating before we called them essential, from the slide rule to the search engine, and the one respect in which AI breaks that pattern. Andy Burnham's technical education reforms, announced this week, which are aimed at exactly the right target and set to arrive in September 2028. And what Switzerland, Germany and Singapore actually built, plus the honest caveats nobody quotes.

Then the Week 30 layoff tracker: BP, Magic Leap, K&L Gates and a developing story at Intel, against a backdrop of four American technology companies cutting nearly 50,000 jobs while preparing to spend $725bn on capital expenditure.

A City investment banker shared an email that should embarrass an entire profession: a law firm ran up nearly £250,000 of billable time on a stock market listing raising just £2m. That's 12.5% of the growth capital, gone before a single pound went to work.

This week, David Richards MBE takes the IPO legal bill apart line by line and shows exactly where AI replaces it: verification, due diligence, document negotiation and assembly.

Then to Sheffield, where LEXcelerate has cut the human labour in a remortgage to 15 minutes per file at a fixed price. And to Centrica, owner of British Gas, which announced 1,300 job cuts alongside a £600m digital and AI overhaul, the clearest sign yet that the automation wave has landed on UK shores, with customer service going first. Plus the Tech & AI Layoff Tracker: Monday.com's AI-first restructuring (~620 roles), Uber's first AI-attributed cuts, and fresh reductions inside Amazon's AGI unit.

Four major AI models landed in three days: Tencent's Hunyuan Hy3, xAI's Grok 4.5, Meta's Muse Spark 1.1 and OpenAI's GPT-5.6. Anthropic returned from a short-lived export-control suspension. And there is no single winner any more: leadership on the frontier now depends on the workload and the evaluation.

This episode includes the complete practical guide, in full: which AI to use for which task across six workloads (software engineering, terminal and infrastructure, high-volume automation, computer-use agents, science and healthcare, on-premises deployment), plus the four-step evaluation to run before routing production traffic.

Also inside: my Yorkshire Post column on walking Boston's Freedom Trail with an AI Harvard historian in my ear; the launch of The Signal Playbook, a free series of production-ready prompt guides; and the Week 27 layoff tracker, where the mid-year numbers are stark: 585,151+ cross-sector job losses in 2026, 185,894 in tech, Microsoft cutting 6,400 including 20% of Xbox, and Oracle's 25,254 locked in via the 10-K.
