I don’t see what you’re describing 🤷 Soon only appears once on the page and not in this context for me.

It appears as a tooltip

Anyhow, where I intended to draw your intention was on https://prose.org/downloads

You can just download the client for your platform (assuming one is available), or use the web one (otherwise), or just build one from the sources I linked (which is what I do), and login with your usual XMPP account. Would you need an account and have to decide which provider to register with, this would come handy: https://providers.xmpp.net/

In this set-up, prose.org isn't hosting your account and will of course let you interact with thousands of users or more, like any other XMPP client.

Those silicon valley tech billionaires are businessmen who, by the looks of it, have completely fallen for their own marketing, and secluded themselves in a weird echo chamber packed with sycophants and profiteers. They are not superior beings. They have no credential nor academic status enabling them to speak as authorities worth being listened to. Anyone with a critical mind and access to scientific literature understands better than them the actual challenges behind "uploading one's brain to the cloud" and can debunk that science fictionesque bullshit.

All there is to this is a bunch of aging megalomaniacs with too much power, except over death, and that scares the crap out of them and makes them say some stupid shit. And I hate that we sanewash this just because they are rich and influential. As a society we should kick them back to where they belong, which is a court of law, for their continued effort in dismantling our society.

Just below you'll find a section about "self hosting (soon)", though you can already use it with your own XMPP account as a standalone client (no questions asked), like I do, or, optionally, with the server-side components (opensource prosody module).

Edit: adding https://github.com/prose-im

See my other comment: if you already have an XMPP account, prose is just another client that you can use however you like, for free (and at that point, everyone should be having an XMPP account, if you ask me). If you don't have an account, they can act as service provider (but this being a decentralized network, the don't want to encourage hosting everyone on the same server).

It is not spam, and you miss-read it. Prose is an open-source XMPP client. They can set you up (host on your behalf) for free, up to a certain point. You can pay for it (there is a commercial offering), or you can use it unlimited and with no extra costs than your own server's if you self-host. It's all being developed there in the open in case you don't want to take my word for it: https://github.com/prose-im

In terms of tech and implementation details, it's been years since everyone has been converging towards the same WebRTC architecture (with everyone bundling/linking the same set of basic components and libs as found in chrome, android, ...). As such, a call between two participants (or as a group with less than a dozen participants) should be as good on XMPP as anywhere else (including the commercial options like Google Meet, Zoom, Matrix, ...).

Where things start getting spicier is in large group calls (dozens of participants or more) requiring the stream to be brokered by a central server (SFU), with stream re-compression and optimisation. Standard-XMPP isn't great for that yet (non-standard XMPP, like Jitsi, on which it is based, is pretty damn good, but unavailable from your regular XMPP setup). Work is going on to improve that (on two fronts, with some XMPP servers turning into SFUs, and with a protocol being designed for offloading AV streams to any willing existing SFU).

No idea what prose is.

Prose is an open-source XMPP client with a focus on large rooms/banquet-style conversations (like IRC, slack, …). It is still in its early stages but already quite usable and possibly a good fit for a subset of Skype refugees.

None of those (except Jitsi to a small extent) qualify as replacements if we ever want to evolve out of the silos we let megalomaniac CEOs build to better control us. So I'll add to the list: prose.org , movim.eu (or anything based on XMPP) and matrix.org (though this one is rapidly falling into obsolescence). The keyword here is federation.

It has already started. Microsoft and Google hiking prices with AI bundled in is both a way to inflate the "demand" artificially, keeping the show going (covering up the fact that nobody really wants that, and even less so wants to pay a premium for it: there just is no miracle AI product/application to sell), and to mitigate some of the absurd imminent losses.

You wouldn't see that in an "optimistic" and sound market.

, and this is just the beginning.
It's bad omen to criticize an opensource project, I know, but in my eyes Matrix is a big technical and organizational failure, for not having succeeded in stabilizing the protocol after a whole decade of unsuccessful explorations, and for having its leadership consistently fail to define clear goals and steer the project towards them (just get it done and working well before trying to make it "peer to peer" or "in the metaverse").

If this is the electroshock that Matrix needs to reconsider its design and directions? good for them. If that kills them? Well too bad, but it's not like they are the only cool kid in town.

I’m selfhosting a Matrix server and have all my Chats from other apps also bridged to there.

Same here, but with XMPP in place of Matrix. For historical context, XMPP was invented about 25 years ago on the premise that people were already tired of having their instant messaging scattered over multiple protocols (rather than Signal, Telegram, WhatsApp, Discord, iMessage now, it was Yahoo, MSN, AIM, ICQ, … then), so bridging is very much front and center in the XMPP world. Over time, people also realized that bridging sucks in general (you either dumb down your client to the lowest common denominator which sucks for yourself, or your client isolates itself from the source protocol enough that it sucks for everyone else).
To add insult to injury, most modern protocols also forbid, by their ToS, the use of alternative clients (which very much includes bridges), and to the best of my knowledge WhatsApp, Signal and Discord will eventually suspend your account on this basis.
Matrix is still trying to carve a niche for itself in this space, and is failing IMO (judging by the quality/security of the bridges they have come-up with, and the recent libera.chat fiasco). I'd say that the situation in this regard in XMPP is only marginally better due to the fact that XMPP had a decade headstart to fail and try over, and I would not recommend using bridges on either of them if that can be avoided.

It XMPP better for group VC?

I'd say "it depends". Fun fact, Matrix uses jitsi-meet under the hood (which is XMPP + a media transcoding/multicasting component that doubles as a relay), and jitsi-meet is my recommendation for this use-case: as long as the central server has good bandwidth, you can really scale up your VC to many attendees. On top of that, XMPP has support for peer-to-peer group VC, with the benefit that hosting is simpler, it doesn't require any central component/relay (but the bandwidth cost is incurred on all participants and you won't go beyond a handful of attendees that way).

I'd rather push for XMPP personally, the matrix protocol has been ~~a dumpster fire~~ in an "almost ready, trust me bro" state for as long as it has existed, and failed to justify its own weight and complexity. But that's mostly irrelevant since they are open protocols and can somewhat bridge with one another.

People don't choose, people use whatever most people around them use. Whatsapp and telegram are both centralized, and shouldn't be trusted because, by the nature of it, they can (and eventually will) turn user-hostile.

Messengers come and go, if we really want to make some progress in this area, we should embrace federated and p2p protocols as the logical evolution. Anything else is just wasting time and user privacy.
