Please HN, let email die. it is unsecurable (universal) in transit or storage (mta's) and because of its reliability and universal adoption a ton of security depends on it like a very rotten and rusted link in a chain even a small child can break.

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.
