I don’t believe that it will replace it but that is maybe a good thing. I’d be Ok with fediverse staying in niche with active user base, because once it’s mainstream it’s gonna attract corporations to enshittificate it like they did it with Twitter or Reddit.
And I’d be cautious with “Internet is flawed”, it’s for us more conscious users but for vast majority of people Internet unfortunately is fine.
I removed all my posts and comments but kept account alive, at best I'll be lurking.
