Well, the feature might just be one of ubiquitous interoperability, much as email provides today. Particularly in an enterprise context: if you want to do some kind of realtime collaboration with someone, you might just reach them directly via Matrix rather than sending them an Email with a link to Slack/Zoom/whatever.

It'd certainly be more compelling if it was an actual feature though. Joking aside, federated machine learning could be an interesting approach, if the value that Matrix provided included a decentralised search engine which could help you sift through all the available content to find the chatrooms and communities you're interested in (and hide the ones you're not...)
