Are you sure? My take on why mass market contact tracing didn't pan out was that it was insufficiently implemented/used. If it were on every phone and on by default, perhaps even mandated, would it still not have worked? I know that many people take significant issue with that approach, but it would have made more of a difference, right?
- teachingassist 6y agoThere are a number of prerequisites, for this to work, that were not mandated in the US and Europe. If someone is informed of a potential or likely infection, but then typically [chooses to/is able to] go about their day the same as usual, then what's the point of tracing them? Initial modelling that showed contact tracing to potentially work assumed: 80% uptake, over 70s to be isolated in any case, and people to strictly follow isolation rules, none of which was considered politically possible in the West: https://www.bbc.com/news/technology-52294896 https://www.bbc.com/news/technology-52294896
- jfoster 6y agoYeah, a lot of it might not be politically or culturally possible. As far as I can tell, it was always technically possible to have very good automated contact tracing, though.
- robrenaud 6y agoAdoption was by far the biggest problem. If Apple/Google just shipped it in the OS and made it opt out, I bet it would have had a significant impact. Not like turning the US into Australia, but even a 10% reduction in covid cases worldwide could have saved 300k lives.
