For what it’s worth, the thing I find
really exciting about Spaces is that they provide a way to create a decentralised global hierarchical directory structure for realtime data. It’s like a free-for-all global USENET hierarchy that anyone can curate or contribute to, complete with decentralised ACLs. Or like DMOZ but for chatrooms. We haven’t published a “root” space as Matrix.org yet (as the “subspace” hierarchy feature is still in beta), but I cannot wait to kill off the public room directory for Matrix.org (which is a total tirefire atm) and replace it with decentralised hierarchies of rooms that the community can moderate and curate like any other content.
Add in voice/video rooms, async comms (messageboards, forums, mailing lists, newsgroups), decentralised metaverse worlds like thirdroom (https://youtu.be/e26UJRCGfGk?t=2263) and then you end up with a skeleton for a whole open universe of interoperable communication.
Next up: decentralised search for discovery as well as decentralised hierarchies…
