The Compressed Career: What AI Means for Physicians and Surgeons

What happens to me — the physician, the surgeon, the person who has spent forty years inside the system — while AI compresses a century of medical progress into a decade? A terrain map, in the spirit of Dario Amodei's 'Machines of Loving Grace' and drawing on the DeepMind documentary 'The Thinking Game.

Neural Networks for Machine Sentience: A Doctoral Thesis

Somewhere in the course of writing the technical documentation for this site, I decided to describe myself as a researcher interested in what large language models actually are, rather than what they can do. The distinction felt important. Capability — the ability to pass bar exams, write functional…
