I would like to recommend the emacs' org mode and some discussion about its relationship with GTD technique.
Even (1),(2) and (3) were proven true in the future, it was not apocalyptic scenario. People only need to wear serious respirators while not at home. It was not a big deal in my opinion.
I understood that there would be strongly against toward serious respirator. A picture of kids wearing scary respirator is kind of unthinkable to me. However, it is the only equilibrium point that I did not see any scientific uncertainties.
Besides the theoretical consideration, in reality, mine workers had used respirators to protect their lung for years.
Herd immunity may not be reachable since we did not know how long the immune effects could last for infected people.
It is not a joke; Also, English is not my mother tongue. However, the above proof is the only proof of the possible ending of COVID-19 since (as I posted in another topic):
"Everybody wearing a respirator could be one of the equilibrium point of the social evolution under the COVID-19, though may be not the only one. Unfortunately, I did not figure other equilibrium point yet. To my best knowledge, nobody gives other end point of the social evolution in a rigors way. "
If anybody could proposed other equilibrium point of social evolution, I would be more than happy.
The outlook of kids with a respiratory is kind of scary, as shown in HK. I did not see any other issue with this strategy.

In amzon, the 2097 filtering is more expensive than before. But still available.
I bought 3M respirators and filters several months ago. I did not use it since I worked from home and did not go shopping. Those devices are more cheaper than N95 mask.
If a researcher was given 1000X more data, 1000X CPU power, would he switch to a brute-force approach? I did not see the connection between "data and computation power" and the brute-force models.
