It also doesn't sound like it even lowers the bar for getting a diagnosis, even with all these caveats. You'd still need a CT scan, in a world where many can't even get a respirator. I'd be more interested in a model that tries to give a preliminary diagnosis (positive or negative) based on data a patient already has with them or can get at home. An image of their throat, audio of their cough, maybe a time sequence of thermometer readings. If we could self-diagnose (or at least rule out some cases) using a smartphone, that would truly change the game.
