The blind, stupid panic over COVID, and the massive economic and psychological damage done by it, and the ongoing complete lack of faith in people who should know what they're talking about is a real life example of The Boy Who Cried Wolf.
Fauci pretty conclusively demonstrated that he ceased being a scientist, and became an administrator, long ago, then he evolved into being an attention whore, and whether he was right or wrong ceased to matter because people stopped paying attention to him (including politicians who told us we had to act like his lies were true or be punished. (Note that every elected official named was a Democrat, not a Republican who resisted the blind, stupid panic from the beginning. They clearly didn't take Fauci seriously, even while threatening legal action against anyone else who didn't.)
Even your own words show you agree with me: ". . . being overly cautious . . ."
Overly means "to an excessive degree". Too cautious. More cautious than is appropriate.
