Not at all! We just need a combination of A) more new instances popping up, B) some people moving to other instances because they like them better or they run faster, and C) kbin.social admins scaling up this instance. It's just an adjustment process.
The good thing about fediverse services is that as long as there are people willing to throw up a server, you can just keep scaling - unlike on a centralised service where if the owner doesn't scale, that's tough.
Yeah, I'm not sure why this thread is showing (to me) as being on kbin.social, but I assume it's actually on a Lemmy instance since OP asked about the Lemmy UI.
On Kbin you can click on the burger menu and then "magazines", or just go to /magazines
