Sure, it’s always going to be easier to do on a centralized platform. However, discoverability just needs to be good enough so that people are willing to use the platform. I also expect that it will keep getting better over time as devs learn how to address existing issues.

Personally, I think that the fediverse is in a very good place already. There are millions of users, and tons of content being generated, and lots of developers working on the platforms. I’d argue it’s in a place where it can sustain itself indefinitely already.
