I could not be happier that wearing a mask is more or less societally acceptable now.
More importantly though it sets a precedent for the future. We now know how easy it is for an airborne virus to decimate us, so even when this virus is over it'll be acceptable for people with immune issues to keep wearing masks "just in case" (similar to Japan/etc, although I know some of that is about stopping other people from getting sick).

Think of what a PR coup it would be for the camera company if they resolved a notorious cold case using their tech.
