If we were masks we will overcome the plague. Will we? The virus does not disappear. When the mask come off the spread restarts. Every Corona virus we have ever experienced is still out there. The only way this virus stops is the old fashioned way of mass immunity. That only stops the massive spread, the virus still remains and will continue to afflict people every year.
No mask. If you are vulnerable you should isolate yourself until everyone else is exposed. Then you will be safe...mostly.
A vaccine? For many people side effects from a vaccine will be more of a problem than exposure.
No mask
Exactly, welcome to the herd.
Generally true but that will take years.
