The Future of Medicine Isn’t Human or Artificial Intelligence. It’s Both.
Healthcare is often presented with a false choice. Human medicine or artificial intelligence. Doctors or algorithms. Technology or personal care. I do not think the future will look like that. The more interesting future is one where technology becomes extraordinarily capable of analysing information while healthcare professionals remain responsible for understanding the person behind it.

Healthcare Was Built to Treat Sick People. What Happens When Technology Lets Us Act Earlier?
Modern healthcare is extraordinarily good at responding when something goes wrong. Emergency departments save lives. Surgeons repair injuries. Medicines control disease.

The next medical revolution…
Medicine Has Changed More in 150 Years Than It Did in the Previous 1,000
Imagine walking into a hospital 150 years ago. There were no antibiotics. No CT scans. No MRI. No modern intensive care. No organ transplantation. Doctors had only a fraction of our current understanding of infection, genetics, cancer or cardiovascular disease. Now compare that with medicine today. We can replace joints, transplant organs, sequence genomes, image […]
Every Medical Breakthrough Started With Someone Questioning What We Thought We Knew
For most of human history, medicine advanced slowly. People observed illness, tried treatments, passed knowledge between generations and occasionally discovered something that worked. But without the tools to properly understand biology, infection or the mechanisms behind disease, progress was difficult. Then medicine began to change. Not because humanity suddenly had all the answers, but because […]
