Maybe to state it another way: The schools that have already closed (all of them) and businesses that have already closed or implemented work-from-home (many of them) have produced the currently observed rates of transmission, hospitalization, ICU/vent needs and deaths. So any projection we make using the current data has to make the assumption that all those things continue, UNLESS we make adjustments to the model account for future actions. In this model, they are assuming that we can do much more - close schools, force shutdowns of non-essential businesses, etc. - but in reality we can't because those were done weeks ago. That's why I think there's a lot of risk that it's an underestimation.
