That was an example usecase, an MVP, to show it works and can communicate via the fediverse.

Comments from the post I linked:

The idea is that every fungi-node also has a UI, yes. So you would be able to browse the AI models - for example if you chat with bot A, and the bot is currently learning with bot B and C, those bots would be visible to you and you could open their UI, too. And it should also show bots with which it trained earlier, too.

This way you could “browse” the resulting AI web via the browser.

Well, its similar to a botnet, but one that is open and transparent. You can browse the different nodes, etc. And you can (at least hopefully in the future) add your own computing resources to the network to participate in the AI training.
