  That's for tracing who came in to contact with one another after the fact. It wouldn't stop people coming in to contact, and it's far too late for contact tracing to be effective for Covid-19 now anyway.

    On the contrary, contact tracing (plus widespread testing) will be necessary in places where outbreaks are eventually brought under control and life slowly starts returning to normal. Of course, many places will need extensive lockdowns to reach that point.

    > it's far too late for contact tracing to be effective for Covid-19 now anyway I think you are right about this and furthermore, non-optional bluetooth tracking is just going to encourage people to leave their phone at home when they go out, especially if they are on the fence about whether or not they are a danger. If they need something they are going to go get it. We need a rapid cultural adjustment that causes people to voluntarily minimize spreading.
