These two topics are related. As pointed out, if we had kept on a rigorous plan, we could have been done already. However, we're really good at declaring victory before we're actually there and dropping stuff early. Which has extended out when we'll actually get to the end. Instead of May 1, or June 1, perhaps July 1 or August 1. A pattern we seem to be repeating at every stage, so maybe August 1 becomes September 1 or October 1.
It's only doom and gloom to recognize that our actions are prolonging the time when we achieve the desired goals as much as it's irrational hope to assume we're done already and can give up up all actions immediately.
Even more fun, both can exist simultaneously for the same people for different contexts. For instance, I can simultaneously plan a waterpark vacation for August, in an environment that I assume will have no distancing, masks, or any mitigations at all. While at the same time not planning a WDW trip with all the same things. Mostly because of the ability to adjust on the fly with that unknown date from above. If we hit the July 1 date, either would be fine. If we say "hold my beer" and drive the date to September, the water park has under $500 on the line while the WDW trip would be $$$. Plus the WDW trip is for an unknown today product where instead of getting traditional value, some dollars are going toward mitigation measures instead.
Let's hope we hit July 1, we need hope.
Let's accept that we may make it longer through our own collective actions.
