I’m currently trying to exit Gmail with all my emails if possible. However many comments are about why I shouldn’t host my own server. So it got me thinking that there should be a new kind of email system not based on all the previous crud from the before times that we still use today.
And indeed, it looks like AI will be the driving force that ends email just like spam did the telephone. Sure the telephone is still around but no one uses teleconferencing anymore for example. We use teams and zoom and such other shitty pay services. So the pool is prime to reinvent email. The users may not see a big difference maybe, but the tech behind it may hopefully be simplified and decentralized as it was meant to be.
The protocols behind email are extremely simple. You can open a terminal, connect to an smtp server, and send an email by typing literally plain English commands.
Its simplicity and decentralization is exactly why spam and phishing is such a problem. Anyone can send an email as anyone else. Protocols for authentication were later introduced to at least mitigate impersonation, but those too are very simple and decentralized.
Maybe you should learn how email works today before trying to reinvent it.
