Terms I use across the essays, defined in one place. Each page holds the canonical definition and links to where the idea gets worked out.
Nearly everything in healthcare passes through one narrow opening. Whatever cannot fit is refused, and refused demand lands on families.
People live their health on three timescales at once. The system is built for the shortest of them. Definition →
Every prior wave of health technology made the existing channel faster. Absorbing the work is a different thing entirely.
The same reading means different things on different trajectories. Alert on departure from the expected path, not a population cutoff.
The connective layer between capable models and useful care. Almost everything below it already exists; almost none of it does.
Diffusion is not paced by model capability. Three gates meter it, and all three open on the harness rather than the model.
Three supply-and-demand curves closing at once, on a schedule already set by demography.
What the medical record becomes when it stops being static. Not a digital twin, not a risk score.
What is open right now, who owns it, and what is overdue. The faster record healthcare does not keep — and the reason coordination lands on families.
Participation on a gradient, from passive to active — because attention is not evenly distributed.
A surface that lives where people live, rather than one they have to visit.
