I mean replace email entirely in the future. But I'd want a client that feels more like current email than a typical direct messenger. The volume of email, in my opinion, doesn't work well in the traditional DM design. I guess what I really want is a more decentralized email that somehow works with my npub and Nostr relays. I don't know how addressing would work globally. I think we'd either have to use forwarding in the short term or replace the current status quo with Nostr. I'm thinking 10-20+ out probably. A small part of a new internet/web I suppose.
