Email as a concept can evolve. We can break backward compatiblity. Call it email v2 and include some killer features. If enough major players and users get involved then it'll happen.
My hope is it'll be something like Dark Mail, yet with a carve out for enterprise recipients to inject their controls and anti-malware before end-user delivery. (To combat spam and malware.)
In theory the giants that already hold the vast majority of all email communications - like Microsoft and Alphabet - are in a prime position to introduce a successor, hopefully this time with a receipt so the last argument in favour of fax dies off. At the same time, they have no proper motivation to do so.
That’s the point about interoperability. If we’re going to make “email v2” (not a terrible idea!), then the considerations that will go into securing it will ensure that it’s entirely incompatible with the thing we currently call email.
In other words: without sufficient clarity, email v2 just confuses people like my parents. Who would be better served by Signal anyways.
