I don't think it is, maybe we are due for another growth spurt but from here on out I genuinely think a critical mass has been achieved where it will simply make more and more sense for people to come here.

Maybe for English and a handful of major European languages, but there's no way I could recommend the Fediverse (at least the Threadverse; I don't hang out on Mastodon) to an Arabic or Japanese speaker. In that area it's still severely lacking.
