So after reading several pandemic books in the last several months, here's what history says will happen: The 'Vid will just stop, before a vaccine arrives. That's what the rest have done since 1918, and before.
And it might be stopping now, but don't know.
An honest retrospective analysis will find that masks, distancing, hygiene, the basic stuff, were marginally positively effective and essentially "free." Lockdowns will be shown, on balance, to be ineffective and highly costly (duh). Biggest negative impact will be mismanagement of high risk individuals in nursing homes and hospital settings (again, duh).
Some kind of genetic vulnerability that makes some individuals more susceptible will also be found. And on the other side, a genetic or cross-immunity advantage will be found in others.
