Yep, the airlines are leading the charge by corporates with the “digital health pass.” But, I hypothesise that all of this will be for nothing, and will not stop the march of Covid XYZ+ and related friends. See all the articles on breakthrough infections at this blog.

Who says that cultural/economic collapse does not have an upside?
