Great job with a sensationalist unrealistic title. This isn't a scenario grounded in fact and it's written by a speculative software engineer. Not a medical professional or epidemiologist.
Sooo this post is flagged, but patio11's conspiratorial epic gets a long day of front page discussion. I'd prefer hn flagged any amateur covid19 policy discussion, it's just a bit embarrassing.
It seems that everyone has become an epidemiologist in the past two months, despite never having even heard of concepts like R0 or herd immunity before 2020.
