The comments in here are confusing. To state it plainly:

Turing machines have nothing to do with the Turing test. They’re two completely different things/concepts, just named after the same guy.

Outside of a massive sorting facility in every supermarket generating no value for the store owner

We already do exactly that for plastic bottles in Germany. You pay 5-30ct premium on each bottle and get that back when disposing of the bottles in the sorting machine. Participation is close to 100%.

For glass, it at least gets sorted into white/green/brown glass to make recycling easier (not in the supermarket though, just containers positioned in residential streets / recycling centers).

Yeah Librewolf is amazing. I dialed some if the ootb settings back for usability, but all the “new” stuff Mozilla adds is filtered right back out upstream, so I never even see it.

1. Signal
2. XMPP
3. Matrix

In that order. I self-host both XMPP and Matrix, and I wouldn’t want to stop using matrix. Spaces, arbitrary amounts of self-chats, and so on are great. I use matrix every day.

But for chatting… It sooner or later fails you. It’s slow. Notifications break. Messages are shown as sent, but somehow do not appear in the recipient’s devices until TWO WEEKS LATER (yeah IDK, happened twice already, in different chats and directions. Best part is, I’m not even federated!). Encryption is great IF YOU KNOW SOME CRYPTOGRAPHY BASICS, and utterly confusing otherwise.

XMPP just works. Especially the calls, holy shit, I had to fight Matrix for so long to make voice and video calls work, and xmpp just… Works. Notifications are way more reliable (as in, have been absolutely perfect). I really like monocles as a chat app on Android. (The downside is: can’t decrypt old messages on new devices, and desktop clients are ugly.)

So why Signal above XMPP?

Because it’s not your fault should something ever break in a vital service. Also the encryption and privacy afforded by it a great.
