I don't think we'll see a federated Clubhouse or TikTok anytime soon.
The correlation between ease of content creation and the success of federated projects is clear, low-effort mediums like text or photos are much easier to participate in than others.
And even then, you can look at the proliferation of TikTok videos on Instagram Reels as another issue.
You can have everything right, but first-mover advantage isn't something you can always buy.
