To me it feels like 2 different set of products, what they are showcasing here seems very similar to slack/teams.

Of course, it would be awesome to have a faster and open source slack, and if I can take notes on the same style as my editor great. So I guess, it would be nice to be able to embed zed in another product.

I think this would be appealing for a company that it's core product is code, like zed, but I do wonder if other companies even need this functionality.
