When discussing the paper I linked this article says "That sounds hard. The good news is that, done well, this measure alone could stop the epidemic. But even if you don’t do it well, it contributes." and correctly calls for combination with other measures. That's my main point, even if it's not as good as manual contact tracing the allegation that this is "tracing app" vs. anything else is just a pointless debate that Schneiers post seems to further. Like the article you posted seems to say, we should improve manual tracing and testing as well but I haven't seen anything in there that would support the Schneier viewpoint on first glance. Looks like an interesting read for later though, thanks for sharing!
