There are rapid antigen tests, less accurate but take only 15 mins. But RAPs would be faster and can scale more easily. What applications for it we'd see will be dependent on what kind of accuracy they're able to achieve, but hopefully they can get some promising results.
If it has good accuracy then on the scalability front it would be unmatched. Like imagine if the gov embeds it in an app of their's, so any time there's an outbreak they encourage everyone (or only those symptomatic, depending on whether it works only with symptomatic or also asymptomatic cases) go on and take the test, like overnight they'd hopefully have a pretty good rough picture of where the virus might be and what portion of the population might be infected.
