Recently I've read an interview with Drosten (the German virologist which came up with one of the Coronavirus tests) say that they're starting to see airborne transmission as an important transmission factor, maybe not a strong as droplets but comparable. This is especially the case in poorly ventilated spaces.
We already knew for instance that SARS is transmitted through aerosols. Then a new thing comes up which is related to the above and is basically named SARS-2 and we forget about the aerosols and instead think we should wash our hands a lot. Words can't express how stupid this is.
After looking closely I found a small move into the wrong direction (maybe caused by something else?!??)
I think it can change something: currently masks are seen as a necessary evil in stores and public transport. They could and should become ubiquitous.
With mask usage in Germany I see only negative trends in the growthrate of both case and death. I think to make them work something has to be changed.
There is a good chance that it now only works as a reverse placebo - it makes people feel confident and pushes them into more risky behaviour - most likely net negative.
