How much does the quality of sampling influence the result with this machine? You're saying testing at work could be done, but what if the swab is not taken properly? Wouldn't that create a false negative?
As the comment made by the other user here says, it will create more waves. Now, that the damage to the economy is greater than the cost of healthcare and lives of a pandemic, that's an opinion you're not backing with data.
Also, I might be biased because I have people in my circle who are at risk, but I think a real solution is more structured than this. Machines + mandatory gloves and masks would be certainly better.
