>>Basically this pediatrician crystallizes the "we don't know what we don't know" status of this disease and demonstrates how a simple test (in the way that complicated things can be made simple) can change many more lives than your own and help us know a lot more usefully. Sorry if I'm not expressing it very well but that IgG/IgM test offers an immediate route back towards normality, as well as more accurate denominator to help modelers with their wildly changing predictions.
Replying to self: I see Tony Fauci is also promoting the importance of IgM/IgG tests as a way to quantify/end uncertainty/path back toward normality. He also predicts mortality will be far less than the alarming predictions that sparked all this. Which is wise of him as you enter week 2 of the predicted 2 week "things will be bad" period when death rates would become overwhelming. How unscientific of real life not to comply with the models! ;-) Lets now hope that things start to get better, not worse...
Meanwhile, cynics predict that if mortality predictions keep being dialed back, climate change modelers can anticipate "Remember COVID-19!" responses to doomsday predictions going forward. The definition of science may revert to challenging hypotheses rather than claiming absolute certainty and stoning evil heretics, which will be positive for society.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
