To be fair, from 2022. I would argue that moderation in Fedi is holding together reasonably well. There are a few popular instances that lots of people think are overly aggressive/purist in their moderation policies, but the people using them seem to like what they're getting.
ATProto is an interesting protocol and there is lots of room to argue about its plus and minuses (and about Fedi/Masto's), but lots of people are already doing that so I won't.
My concern isn't technology or culture, it's money. At the moment, ATProto is existentially dependent on Bluesky PBC, a venture-funded startup ($100M from Bain Capital). There are people doing good work to make it more decentralized, more power to them, but at the moment it's still deeply centralized. And it's hard to see what the business model is that will support what Bsky PBC does at a global scale. Eventually Bain will want to see a revenue stream that justifies their investment; maybe there's a way to do that that doesn't involve enshittification but it's certainly not obvious.
You can dislike the instance-centeredness of Fedi/Masto (seems to have worked OK for email over the decades) but it's an actual thing that's actually working. And offers account migration without losing followers if you don't like the instance you're on. And has multiple really excellent client software packages. And seems to be covering its costs through a mixture of Patreon, co-operative & nonprofits, some Euro-gov help, all without any VC input. It can't be bought or owned by anybody.
Put another way, this is a really interesting space. But the technology is less interesting than the culture, and the culture is less interesting than the m money.
I'm highly unconvinced of the proposition that most homeless are severely mentally ill; the data I've seen doesn't support it. That's some of it, and also addiction. But a lot of them just can't make the rent.
I'd like to see a few links to support your assertions in the first paragraph because, with respect, I have not seen evidence which supports them.
On the other hand, multiple jurisdictions have run trials of UBI (universal basic income) and unless I misread the reportage, the results have been good.
Well, healthcare is an increasing piece of government spending all over the world, and the population is aging, so politics and policy aside, that number is going to go up.
