I think something like Tim Berners-Lee's (Inventor of the www) Idea of linked data will emerge on its own, as a consequence of a fundamental shift in how data is processed and stored. So we will shift from data stored in separate servers/databases to data stored in some kind of network whatever that may be (LLMs, embeddings etc.)

You will then probably no longer need websites, because you only need the data itself which is now "fluid" in the way it can be presented to you.
