Consider that many governments with professional public health departments, including those of the richest countries in the world, downplayed the unfolding disaster, completely blew it on containment as a result, and are now reduced to using _extremely_ expensive lockdown measures to try to buy time until someone can come up with a better idea.
Meanwhile, plenty of randos on the internet did the straightforward epidemiological math in January/February and correctly deduced what was coming.
I think a clearer lesson is that, sometimes, the designated professional experts will fail to outsmart a fairly simple and very well known system of differential equations.
If you find this conclusion terrifying, well, I agree.
