Not a single messaging app I’ve used comes close to email. And I can’t use one messaging app, I have to have 6! I would be way more willing to move on from email if a solid viable alternative came along. XMPP, for example, is still too ephemeral and barely anyone uses it.
As far as XMPP for business, there are still things I really appreciate about email - threading/subjects to isolate different interactions being one. I would still love to be able to have it as a tool for bvb comms. Email is a very nice archival tool for both correspondence and documents. It's one of the few things in my life that is mostly organized and gives me easy access to things I need. Recently someone from a government agency said "you never sent x document" and I was able to go back in my email and say "yes I did on this date, I will send it to you again".
(Ditto with Facebook Messenger and at least one of the Google chats ?)
You seem to have missed the point of the article. Email is a necessity - there is no alternative.
But good luck moving people off email
E-mail is grotesquely expensive to manage because of its weaknesses and its use as a vector of attack.
The best replacement solution is an organisational portal that people use to communicate with the organisation and upload/download documents. Some governments and banks have already been handling interactions with external entities and citizens/customers this way for years.
The upload and download tunnel is secure, the receiver can scan the uploaded information (detonate in a sandbox if necessary), and the sender can trust the messages and documents that are downloaded.
I am very concerned how people here are stating how good, simple and reliable it is. They are not wrong but so is IPv4 and the C language. Sentiment has no place in a building a secure and proper future technology.
