That seems more like an argument to make more data available. Presumably more people at risk of a stroke can be notified by an algorithmic assessment than could be possible trying to fit them all through actual physician screenings, no? In a public health sense, it would do more good in terms of lives saved, even if algorithmic errors cost lives in some specific cases.

I’m familiar with programs that at scale that have been demonstrated to predict certain negative health/behavior patterns.

From a medical point of view, you can assume a 10-20% probability of a negative outcome. If you layer on other factors or behaviors in the persons life, the probability of a bad outcome approaches 90%.

Problem is, you need deeply intrusive data at scale. What are the consequences of a organization with Google/Facebook capability who also is your AI doctor? It’s easy to foresee complications.
