Centralized or not, app-based contact tracing has not worked anywhere. The countries that do successful tracing do it manually, and when personal data is used, it's only infected people's data. Taiwan's minister explains here: https://www.youtube.com/watch?v=ScIVe6STVxI https://www.youtube.com/watch?v=ScIVe6STVxI . No need to bug the entire population for this. As long as new cases are very low, manual tracing by trained personell is superior (because of all the edge cases) and sustainable. If you have too many cases (>100s per million) you re better off shutting down anyway. What are all these apps other than a new kind of surveillance toys, which we know will be force-installed in many countries and will most likely be abused? Maybe it's solutionism that appeals to world leaders for safety theater. https://www.brookings.edu/techstream/inaccurate-and-insecure-why-contact-tracing-apps-could-be-a-disaster/ https://www.brookings.edu/techstream/inaccurate-and-insecure...
