Web 3.0 is also used to describe a path towards the evolution of artificial intelligence networks, which can ultimately think about networks in a way similar to humans. However, some people express pessimism about this, believing that it is an unattainable idea. However, big companies like IBM and Google are already using new technologies that are providing amazing information, such as predicting future popular singles by mining data from school music websites. At the same time, some have also raised the question of whether intelligent systems will be the driving force behind Web 3.0, or whether intelligence will appear in the form of humans, that is, the people of a certain system (such as collaborative filtering services like Delicious, manually extracted network resources like Flickr and Digg), and how they interact with each other.
