No need to speculate, there’s an article with valuable information on this very topic linked in the OP.

In a blog post, Discord laid out its plans to publish ‘Server Web Pages’ for every discoverable server on Discord by default. These are bespoke web pages that give a preview of a server’s contents before forcing users to hit the join button. There are already several of these pages live, typically for huge online games like Rust or Dead by Daylight. These pages will be discoverable on Google, and will display a summary of the discussions going on in the server.

But while these Server Web Pages will be going live next month, another update is coming in December that’ll allow answers to questions to appear in Google search. According to the blog post, “Answers to questions your members sent in public channels can be found in a web search, in their own words. Server admins decide which channels take part, and server members can choose whether their own messages appear. Usernames and avatars will not be shown alongside these messages.”
