Well if we're going to get into this, I'll say that the people I've been paying attention to have been pretty damn accurate about the seriousness of this since the early going, and about masks (which I've been wearing since March), etc.
I think a lot of the "the experts were wrong!" people fail to grasp that this is just what science looks like, live. When you're dealing with a new, relatively unknown virus, you learn on the fly. We can speak definitively about a lot of other viruses because we've had years or decades to study them. We know how they spread. We know how to best contain them. This was all new, so of course "experts" will be wrong. It certainly doesn't help when the most visible experts and expert institutions in the country are undermined and obstructed by politicians.
I have no idea what the science says with regards to this subject and the people I trust, who seem to have a pretty good handle on this in terms of understanding what is or isn't a big risk, haven't said anything. So, I don't know. If it's just an optics thing from politicians, then f*** that. If there's some real science here, it would definitely be something I'd like to know more about it.
But to just dismiss it out of hand is silly.
