In Elon's recent convo with Bill Maur he stated Twitter was stabling out. Many things can coexist, twitter like facebook has a large user base that businesses will continue to advertise and utilize. Nostr seems to be farther up the graph and the super spreaders may not be able to get a critical mass to use it. Bitcoin is harder than solving a rubiks cube in my opinion whereas using the dollar and twitter/ tictoc/ facebook is still easier than navigating even google.
