I admire your optimism but the feedback from the health service is that we are in for a nightmarish winter. We are still in the first wave so spikes in this would appear to be the more likely than it disappearing in the next few weeks. It seems the worry is that the relaxing of lockdown will cause an obvious spike and this looks likely to run in parallel with the flu season.
I 100% hope that you are right though.
Given that everyone from old to unhealthy , bald and whatever else is coming from the experts , I don't really listen to every new thing that is theorised.
I go on the basis that there has been mass gatherings over and over since the start of June and there hasn't been any actual flare up. Pick the Leicester one out for example and it's lots of people in one location which is easily explainable. We haven't seen a mass surge in London or Liverpool following the gatherings.
By all means avoid them still for a while but more and more normality returns and all we get is isolated cases. Within a month it will be all fine again.
I also believe that the virus may never go away without a vaccine but we won't see levels that we have.
