Healthcare is the most regulated, slowest-moving and institutionally defended industry in the modern economy. This week, all three of those defences cracked in the same direction.

Three stories.

One. The FDA has announced AI will monitor drug trials in real time. AstraZeneca and Amgen are already named as proof-of-concept partners. The Commissioner publicly concedes that 40 per cent of clinical trial time is "dead time" AI will dissolve. This is not an efficiency programme. It is a regime change. Britain's MHRA has nothing comparable live in 2026.

Two. The patient builds the model. Two years ago I sat in an A&E corridor with a family member showing suspected stroke symptoms, using AI on my phone to think through differential diagnoses. This year I have built a personal AI health model on my own data: Whoop biometrics, private blood panels, every NHS record I could obtain. GPs in both the US and the UK have missed things. They are human. The system that asks them to evaluate a multi-decade health history in eight minutes is the problem. AI does not have an eight-minute limit.

Three. The Fifth Wave. The single greatest achievement in human history is the doubling of life expectancy from 32 years in 1900 to around 73 today. Four waves of breakthrough got us here. The curve has been flat for two decades. The case for AI as the fifth wave. Why Silicon Valley's 150-year claim is wrong on timeline, but the squaring of the mortality curve is the real, achievable prize.

Plus the weekly Tech and AI Layoff Tracker. Cloudflare's first mass cuts in 16 years. Coinbase, Freshworks, Upwork and BILL Holdings. Microsoft's 900-million-dollar voluntary buyout programme. The polite fiction of "AI-assisted workforces" is over.
