Yes, and I agree that it's always important to keep that possibility in mind. I am generally keenly aware of uncertainty normally shy away from bad bets (predictions). But taken too far, that principle leads to abdicating our responsibilities as citizens in a democracy, so while I was definitely chastened by the experience I will kindly decline the invitation to shut up: I choose to get better instead. The sum total of my influence on this matter has been, at worst, to encourage quicker and more widespread adoption of home tests, which falls very short of pernicious. I'm quite puzzled by P5fRxh5kUvp2th's vitriol - maybe he or she is ardently pro-mask? Since I alluded to my low opinion of mask mandates (which I stand behind), that could explain it.
