What is Web3? Explain like I’m 5

People don’t mean a specific app when they say “Web 3.” Instead, they mean a group of projects that are being funded by cryptocurrencies and are working together to build a new decentralized internet infrastructure. These services could include decentralized social media platforms where users can freely debate and express themselves without worrying about being censored by a central authority, as well as decentralized data platforms where users can access information that is not controlled by a single entity.
