Schneier makes an excellent point about the usefulness of the contact tracing apps that I (personally) haven't seen much elsewhere.

> As long as 1) every contact does not result in an infection, and 2) a large percentage of people with the disease are asymptomatic and don't realize they have it, I can't see how this sort of app is valuable. If we had cheap, fast, and accurate testing for everyone on demand...maybe. But I still don't think so.
