Web 3.0

No central point of control
Since middlemen are removed from the equation, user data will no longer be controlled by them. This reduces the risk of censorship by governments or corporations and cuts down the effectiveness of Denial-of-Service (DoS) attacks.

Increased information interconnectivity
As more products become connected to the Internet, larger data sets provide algorithms with more information to analyze. This can help them provide more accurate information that accommodates the specific needs of the individual user.

More efficient browsing
When using search engines, finding the best result used to be quite challenging. However, over the years, they have become better at finding semantically-relevant results based on search context and metadata. This results in a more convenient web browsing experience that can help anyone find the exact information they need with relative ease. Web 2.0 also introduced social tagging systems, but those can be manipulated. With smarter algorithms, manipulated results can be filtered by AI.

Improved advertising and marketing
No one likes being bombarded with online ads. However, if the ads are relevant to one's interests and needs, they could be useful instead of being an annoyance. Web 3.0 aims to improve advertising by leveraging smarter AI systems, and by targeting specific audiences based on consumer data.

Better customer support
When it comes to websites and web applications, customer service is key for a smooth user experience. Due to the massive costs, though, many web services that become successful are unable to scale their customer service operations accordingly. Through the use of smarter chatbots that can talk to multiple customers simultaneously, users can enjoy a superior experience when dealing with support agents. Reference:
