If a new a Twitter/Bluesky replacement is to promote civil discourse, it will need to _restrict_ reach as a core feature. Which... seems antithetical to a social media platform. But as long as "enragement = engagement" holds true, each new social media platform will eventually devolve into the same kind of cesspool as its predecessors.
People will just go back to Twitter/X, again, because despite all the falling-sky predictions it remains the single most important social media platform of our day. Governments around the world announce actual world-changing news on it - kind of all you need to know.
But...restricted reach is exactly how Bluesky works. People you follow show up in your feed, and only them. You can look at other feeds that are not as restricted, but you are making that choice.
