not only that but dominant platforms have always evolved, going from mass media consisting of newspapers, to radio, to newsreels, to broadcast television, and then to primitive dialup services like AOL and Prodigy. I would expect this will continue to evolve, from Twitter, Facebook, Instagram, TikTok, etc, to standards-compliant interoperable services.

The audience, or in other words the public, always catch up and move to the next dominant platform. This is one reason why I think arguments about network effects are one to be taken with a grain of salt. The public will go wherever the content is. Twitter's audience is not going to remain as valuable as it previously was (ahem, mismanagement may be one reason for this).
