There have been several seemingly "world changing event" over the past 102 years starting with the Spanish Flu. 20-50 million died, but soon life went on and things got back to 'normal'. The 2 World Wars were certainly events that altered civilization especially the holocaust, 6 million Jews died, but soon things got back to 'normal' and life went on. Those events did foster changes in the way things are done and the way lives were lived for many but I believe that a few years from now this too, Covid-19, will be part of history that scared the shit out of us but life will go on and things will return to 'normal'.
Religions and cults thrive went things like this happen but in the end I believe that rationale and sanity will prevail!
just saying!
