I think you're probably right about this - they will change course more likely in six days than six weeks.
But whether that will turn out to have been the right decision I think is difficult to say. I expect a massive surge in confirmed cases, but that's going to be from expanded testing. Will it translate into an overwhelmed system? I wonder. Dangerous guessing game, I think, no matter what you do.
I'm currently in self-imposed isolation from everyone because I'm pretty sure I have a chest cold and I don't want my kid to get it. Isolation is about as proven a technique as I can think of and it's hard to imagine rejecting it. But then, failures of imagination are common; maybe I'm experiencing one. If it's just a cold, maybe I should want him to get it. Maybe exposure to whatever I have will improve his immune system. Maybe I have a different coronavirus that will confer some kind of partial immunity as I have seen theorized a lot recently. Who knows?
Anyway, really interested to see how it plays out.
