I've been wanting to get a #BeagleBone AI for a while. I saw one for sale, so I ordered it. I can't find an MSRP, but I can guess that I paid more than that.
I think there are still a couple of projects around making a !RasPi, #BeagleBone, or similar SBC the host of one's primary online presence. I just don't think that--given asymmetrical connection speeds and ISP interference--it is a workable solution, even in most Western countries. When you consider the poor countries where the only Internet service is mobile devices, there's no way it can put "most" people in control of their data.
We probably need to combine multiple approaches, where most approaches are hosted outside one's home or physical control.
@lnxw48a1 a simple, single-user XMPP server could be useful on a VPS too. I'm using self-hosting in contrast with community-hosting, not in contrast with remote hosting. But there are, at least in theory, many advantages of running a personal server at home on a #Pi, #BeagleBone, or old laptop. It's much cheaper, data privacy doesn't rely on trusting a remote host etc.
