"Better, cheaper, faster: choose two" (sometimes called the project management triangle) is false in the NHS where much of the system is so far from being optimal that everything could improve: hsj.co.uk/daily-insight/…

China is currently not trying to fix its healthcare system step by step, but by attempting to leapfrog it entirely! Only about 10% of China’s medical institutions offer truly top-tier care, while across its ~33,000 township-level health centres, only around half of GPs have a university degree. Patients know this and regularly bypass local services to seek specialists in megacities such as Beijing and Shanghai. Instead of slowly expanding the medical workforce, China is moving towards a model where shortages in primary care are addressed through telemedicine and AI. This mirrors how the country largely skipped widespread credit card adoption and moved directly from cash to mobile payments. Telemedicine has already reached an enormous scale: 1) JD Health reports 200 million active users, with over 500,000 online consultations per day 2) Ant Group’s AQ app has served 140 million patients, with nearly 1 million doctors offering services via the platform Now the government is going one step further by making a plan for “full coverage” of AI-powered diagnosis and treatment tools at grassroots health centres by 2030. What this suggests is that digital health is more limited by culture, incentives, and system design, than by technology. Source (behind subscription): economist.com/china/2025/11/…




Really smart from @pkedrosky — the *descriptive theory* of historical bubbles and busts as useful installation surges (over-investment and a capital wipeout that left behind useful infrastructure) now risks becoming a cultish *prescriptive excuse* for irresponsible behavior.
