Test outcome is only a snapshot. At the point of testing. 1 second after that you could be infected!
So unless we have capacity to continuous test 331 million Americans daily - number 6, test everyone is empty talk.
After testing, we need to have effective quarantine for those tested positive. At least 20% of those positive would need to be hospitalized - doubt we have that many beds. And the other 80% must be quarantine - Not many houses have attached bathroom for each bedroom - many kids share bedrooms.
Can Benioff give something workable!
