I like to focus on the tangible aspects of assessing where we are, and, where we're likely to be going.
I fully appreciate that for the vast majority of people (and for good reason), the responses and developments have left a lot to be desired as well as many more questions than there are answers. Unfortunately, such is the case for a once a generation crisis. Indeed, it remains to be seen how the world will come out of this in the months and years to come.. I'll leave that to the conspiracy theorists, however.
One thing I will add in response to your comment about the number of years required for "tests" -and by that I assume you mean the trials- it is true that these can and often do take even up to a decade. But we must remember that this not only a public health crisis, but a global pandemic. Enormous amounts of money have been funnelled towards accelerating the research and development of these vaccines, and very real tangible scientific breakthroughs have been made, in unprecedented time no less.
We remain a resilient species, and while I remain sceptical that we will survive in the longer run due to other more egregious self destructive behaviours, I do believe we will come out of this particular crisis relatively unscathed.
I hope with all my heart that we get through all of this and can continue.
