POP and SMTP aren't asynchronous though, if an SMTP server is offline the senders only recourse is reattempts
This is why email servers don't belong on phones and neither do lightning nodes

i think that since you are comparing apples to oranges what about instant messaging clients on phones
sure, most of them use servers
but keet.io you only need to be running the client on your desktop and it picks up your messages and your phone can grab them too
for group chats anyway, i don't think they have (nor simplex) made it easy to share identities but with nostr i could do that tomorrow if i could throw together a quick GUI for a nostr chat client, it's beyond easy on the protocol level
i just osted a screenie of my relay's current memory usage, it's less than an average web app
so yeah... actually, things have progressed a long way since it was necessary to have hosting to run peer to peer services
That's still not async, you're running a daemon and it still has signaling servers
Also keet afaik is another clowny DHT scheme that won't scale
your argument seems to be that you can't run the internet without professional, educated asshats in data centers
or what
you are just a troll, good bye
Your arguments are that you don't understand how anything actually works 🤷♂️
