Also think that AI Discover or Discoveries is confusing, giving there’s Discourse Discover already.
More semantically, I find Discourse Discover a good name that conveys that I can discover new communities.
I struggle with what AI Discoveries are really meant to say on the other hand. It sounds as if the program has some explorer spirit and is out to discover the untold depths of forum content. Or if it’s taking me on a tour of unexpected insights and change of personal perspective. But I’m searching and all I’d want are good search results. Why not just AI results or Natural language search?
In the same vain, I do find the 
emoji or icon for all things AI a bit hyperbole.
I’m not against the features, but I’d find them much more agreeable and straightforward to use without these anthropomorph touches and magic glitter.
