To be realistic, it seems impossible.
However, there's nothing so impossible in this world where things happen surprisingly, especially when the product is a perfect answer or solution to a problem + good & strategic marketing.
Just like I said in this post, if Leothreads can gather 1/100th of Twitter's present active daily users, then Leothreads has achieved a great feat.
Vast population on social media aren't bothered about Blockchain, neither are they concerned about the Web 2 & web3 fight or the Centralization and Decentralization dichotomy.
They are just interested in a Social Media that works well for them. So, if Leothreads addresses this and markets the product like this... we will get a wider audience.
Blockchain integration and all the beauty will be an icing to the cake.
