I'm pretty sure the AT protocol is meant to solve this. Not so sure that any of the big players in the social media industry are enthusiastic to use it, though.
It also reminds me of the Onion article "Sumerians Look On in Confusion as God Creates World".

Sadly, convenience always wins, and most people need a better reason to "switch platforms" (which is, ironically, what moving your socials to atproto/fedi means). Together with the dismal state of general education on digital independence, such revolutions just won't happen for the overwhelming majority of internet users. The lack of GPG usage is a common example, but people don't even own their email domains :)
