We actually will not know even in retrospective, because the alternative scenarios will not play out.
I am not saying everyone should get sick at once, a certain period of isolation is acceptable - for now.
In the long term, it is not reasonable to isolate everyone. Covid-19 will stay with us for years.
Possibly?
> Going by the mostly elderly population on the Diamond Princess, mortality with proper treatment is going to be significantly lower than 1%.
If we're all sick at once can we all get proper treatment?
We're all making assumptions and treating our ideas like they have to be true. We still don't actually know, we will only know in retrospective, and that's important to keep in mind. We can't know what's going to happen, and I think we need to be more cautious than optimistic. Where's the line between that an insanity? I don't know, but we can't act like we know the math, especially when we're getting equal and opposite information every day.
