I hate to rain on a good rant, but do you have any actual data to back up all these strong assertions? Contact tracing (the old fashioned kind) works quite well when it's done aggressively and case counts are low. However, for most of the Western world neither is true, and throwing Bluetooth at the problem isn't going to help. Neither can it magically prevent infections from people who don't know they're contagious, which we've come to realize is a significant feature of how COVID spreads.

Agreed, Australia and NZ are doing aggressive manual contact tracing (in addition to the app that was released in Australia in April). Last I checked NZ had managed to link all but two of the cases back to the one source. Victoria (AU) likewise has managed to trace the majority of cases to a breach in the quarantine hotel, because security guards weren't wearing PPE and were sharing a cigarette lighter (if I am correct). It's part of a tool chest, as is the lockdown, the masks. As much as I am glad not to be locked in Australia/NZ right now, I am proud of how they've been handling it in general.
