Humans are the factor.

Yep this sometimes gets lost, human behavior is a very big factor in supercharging this in my view.

Politics injected into this has amplified this among certain groups as well. See Florida, Mississippi etc
Murdocks millions of devoted media consumers, influencers finding ready patronage, and unsocial media.
Then a kind of warfare as nations may also have been feeding misinformation to make them look good.
So Australia has another super-spreader event in pointless protests, and when they go back to suburbs or countryside ?
Will it be just Delta, or Delta plus people readily spreading it ?
Our chances are much better if we are the generally more level headed nation we think we are ?
