My perspective as a dual citizen French/American tech worker living in the US: the fact that there aren't digital Apple Wallet/smartphone covid passes is such a joke. Farcical levels of stupidity, something you'd read in an 'Idiot Hero' trope novel. It is such a failure to capitalize on the available technologies at our disposal as a global society.
Instead I have a piece of shit paper document from the CDC that isn't even a standard business/credit/debit card size (!) so it is already in tatters, with a grease stain (my dynamic life has failed me). Nowhere even asks for it, so enforcement is a failure in and of itself. The vaccine should be mandatory and there should be a sleek digital pass so I can not have one extra piece of paper to carry around because of inept structural decisions around how to implement a post-pandemic lifestyle. So stupid, I don't know how these social planners have jobs.
