I don't think so. No Twitter clone, or Twitter consept is going to replace Twitter.
What made Twitter big, what made Instagram, Facebook and Snapchat, big is that they all brought something new on the table. Blueskye, mastodon etc. don't. It's just the same.
People that are active on Twitter have spent years to make a following, and there are no reason to go over to another app and create that same following again. Why spend the time and effort when Twitter still is a thing.
Plus people have been talking about leaving Twitter for a year now, but few people actually have.
Mastodon/fedi certainly brought something new to the table (microblogging with close-knit communities), it just isn't a technical feature nor something that's meant to "scale".
