Well, after leaving the Web 3.0 failed semantic hype [1] I find stuff such as ChatGPT and LLMs already working. For example, today I started looking to buying a TV stand of good quality. Started an all classic series of search on Google with the typical ads and compiled lists on top. After half an hour feeling running in circles (the results were about the same companies) I fired ChatGPT, asked about a list of places, asked to expand the list three times and voila! all concepts that I remembered about Web 3.0, RDF, triples, FreeBase [2], etc where unnecesary now for reaching Web 3.0.
