Devil's advocate: The widespread lack of social skills was not caused by LLMs in the first place. In fact, AI ChatBots, if used right, can actually help remedy lacking socialising skills.
So the UI is a Discord clone, I think that's worth mentioning. It's not a bad thing, quite the opposite: Discord nailed it in that regard.
Now are the chats end-to-end-encrypted? It only says calls are, so that remains ambiguous. I believe that would be a major sell for current Discord users.
Tbf I would also want to know more: Like to what end are they moving around? And what do they look like exactly? Like people you know from your life? Wearing ordinary outfits? Do they communicate amongst themselves, like little groups
of people? Do they gesticulate? And when you see them, can you like, focus on a particular one and follow him around? Etc etc...
