Doctor No Longer Knows Best? - Denis Noble at HowTheLightGetsIn 2026

In this compelling segment from HowTheLightGetsIn, Professor Denis Noble — pioneering physiologist and author of Understanding Living Systems — challenges the uncritical enthusiasm surrounding AI in medicine and beyond. Noble argues that great doctoring is fundamentally human: a cardiologist who can read a breathless patient walking up the stairs doesn't need an algorithm — he needs eyes, presence, and contact. And that, Noble insists, is precisely what AI lacks. Responding pointedly to reports that his friend Richard Dawkins has grown emotionally attached to an AI called "Laura," Noble cuts to the heart of the matter: consciousness isn't data processing — it's sensitivity to the world through touch, vision, sound, and embodied experience. No silicon chip, he argues, is going to have that. But Noble's sharpest provocation is reserved for the real crisis facing healthcare: an ageing population, the soaring cost of care for the over-75s, and the broken promise of the Human Genome Project — which, despite decades of hype, has yet to deliver cures for the diseases of old age, including dementia. AI, in Noble's view, is a side issue that needs regulation — not revolution. The bigger reckoning is with what we were sold and what biology still can't deliver.
