Who knows.
It depends on whether the tech has standards & protocols that seem like it will have long term sticking power, & be something we can grow & shape & nurture forward.
There's a lot of very smart developers who seem to have gotten a lot of license to make new protocols & systems that made sense to them, and so, yeah, I'm excited to see what happens.
But there's a lot of very promising new personal-scale communication systems. ActivityPub, Nostr, and now @ are all promising protocols. Anything could happen. But I do expect to be exploring BlueSky for at least a while.
I wonder if everyone can agree that "working together" should be a common goal.
All of these protocols are noble efforts. What I wish Dorsey had done though is establish a council of stakeholders to build a sort of "lingua franca" for them. It's obviously wishful thinking, but I think a lot of people are largely making the same thing. If we all want to be able to talk to everyone else, it doesn't make sense to treat this as a competitive arena.
We'll just have to see where things go. My guess is that people will converge back on an RSS-style standard that prioritizes openness, but it's anyone's call. We've settled on questionable standards before, we may do it again...
What's charged is my mindset. I'm no longer coming with such a view of scarcity. Of insisting we work together.
You know who gets everyone in a big meeting room & then decides what to do & builds that architecture out? Corporations. In contrast, I think the organic growth model is a huge win here. We can cover more ground, better assay where the rich & nutritious veins are, better explore the many ecosystems of possibilities with an organic model.
It's all still so early, we're so young. ActivityPub, Nostr, BlueSky/@.... they barely have antecedents and none are proven. We are in free-form mode, none of us know what to do yet. You mention RSS, but that's a read-only medium. That attempts to explore the bounds of that didn't get that far: Google Buzz, the Salmon Protocol. OpenSocial. They weren't necessarily bad techs but we never really figured it out, democratized it, pulled it off.
We have multiple different explorers now, and I like it. The ability to keep making useful growth, is, I think, what counts here. ActivityPub has shown some decent flexibility in going across-mediums, but we don't have a ton of extensions, a ton of new modes for it (I think Akkoma, an Elixer-based fork of Pleroma is the most boundary-pushing, and reaction-emoji is their main defining claim to fame). BlueSky is brand new and we have no idea how far it'll go, but it also has a lot of really neat compelling web-oriented ideas in it's core, of signed DIDs that let it be web without having to rely on http:// and dns:// and give us self-sovereignty. Nostr I think is incredibly fantastically compelling, for it's hackability, and what a huge roster of incredibly smart & sharp "Nostr Implementation Possibilities," (https://github.com/nostr-protocol/nips). What a beautiful phrase that captures so much essence of where we are: finding possibilities.
Right now, we need to emerge a shit ton of complexity. We need really wild off the wall stuff. We need lots of ideas & possibilities. We need growth & exploring bounds. Once we have some actual experience building these things & running them as smaller scale individual/microcollective operators & peers, I think then we can focus a lot more on narrowing down & coming together & deciding where and how to meet.
