What is web3? What are the dangers of Web3?

Web 3.0 is a decentralized version of the web that removes intermediary applications between people and software, giving users more control over their data. Because the data will be in the cloud and not in the hands of an application, the security of users' data is increased. Because information can be stored in many different locations at the same time. Users can communicate and connect with each other without intermediaries. No one other than those two users can know and control this communication.
As for the dangers of Web 3.0;
No intermediary application in connections increases anonymity. This makes it difficult to identify the culprit in malicious uses.
The fact that most countries have not yet made legal regulations on web 3.0 may lead to legal uncertainties.
Storing data on decentralized networks can lead to data loss.
