A pretty cool thing about the Fediverse:

It will still be around in a decade. Even two decades.

Usenet still exists. IRC still exists. Email still exists. When you build platforms on open protocols and standards, it doesn't actually matter what corporations try and do to enshittify it. So long as there are people who are still willing to run instances, and users who still want to talk to one another without going through some corporation's platform, it'll still be here.
