Or maybe tracing was just bull$hit?-----"If contact tracing can't provide clarity for the most protected, observed and scheduled human on the planet..."

"I heard about President Biden's COVID diagnosis and found it interesting that contact tracing was unable to discover the source of his infection. 

If contact tracing can't provide clarity for the most protected, observed and scheduled human on the planet it leads to a bit of humility when one thinks about applying it to an entire population.
I wonder if all the emphasis on it during 2020 overestimated its efficacy or underestimated the airborne virus. 

Just processing what lessons should be learned while I stain my deck today."
