Interesting read, somewhat enlightening.
But IMO, from the point of view of interoperability, it was bad enough having competing corporate social networks. We don’t want to replace that with competing open meta-networks. And yet ActivityPub and ATProto seem to use completely different paradigms, which would make bridging them pretty hard. Frustrating.
This seems to be the argument that the web was designed for documents and that we should stop trying to shoe-horn apps into documents. Hard to disagree at this point, especially when the app in question is, say, a graphics tool, or a game. I still think that, in the case of more document-adjacent applications, a website implemented with best-practices progressive enhancement is about as elegant a solution as is imaginable. Basically: an app which can gracefully degrade to a stateless document, and metamorphose back into an app, depending on system resources and connectivity, and all completely open source and open standards and accessible. That was IMO the promise of the web fulfilled: the separation of content from presentation, and presentation from functionality. Unfortunately there were never more than a tiny minority of websites that achieved this. Hardly any web developers had the deep skill set needed to pull it off.
I was once skeptical about WASM on the grounds that it’s effectively closed-source software - tantamount to DRM. But people reply that functionally there’s not much difference between WASM and a blob of minified JS, and the WASM security can be locked down. So I guess I accept that WASM is now the best the web can hope for.
