I don't see Bluesky overtaking X in the future. Bluesky just came around and it hasn't really been making that much waves.
Bluesky and Threads might have the same thing in common because the way Threads was hyped looks as if it will be on the top list but nobody is talking about it again.Honestly, I don't know if Bluesky is going to become bigger than Twitter/X because I haven't started using it yet. I've been hearing how it's getting so many users but it's only time that will tell if it can beat X.
Well, I don't know if there's any social media that will be much bigger in the future like Instagram, Facebook or Twitter. These 3 are already taking the top list and others can follow with less number of registers.Bluesky might be a big thing in the nearest future, but definitely not going to overthrow X. It is hard to foresee any social media that can do that now.
