Web 3.0: Have we arrived? - Learn more about Expert System

In 1999, Tim Barners-Lee stated: "I have a dream for the web [in which computers] become capable of analyzing all the data on the web. A "Semantic Web", which should make this possible, has yet to emerge…" Since then, the idea of a semantic web has helped generate and sustain our expectations around the web 3.0. Eighteen years later, I wonder if we have finally realized that dream. Have we crossed the line where computers, and their software, are really capable of analyzing all of the data on the web? And if we haven't completely crossed that line, at least we have a steady foot on it.
