I want to give a shout out to exposure notifications, the API Apple and Google created at the beginning of the pandemic. Well scoped. In close collaboration with domain experts. Privacy protecting. Measurably helped, maybe not as much as hoped, but still. And now being responsibly shut down, as promised.

We should praise folks when tech is done right. I want to see more of this responsible deployment of tech.

@ben Ben, aren't there other communicable diseases that we could prevent with this technique, though?
@evan my sense is it's most useful for emerging diseases or for diseases that have significant asymptomatic transmission. Plus you need a robust testing infrastructure, cause self reporting is weak and leads to false signals. So... Maybe? But i like that they're using it conservatively.
@ben that makes sense!
