Pure discussion, because I saw many people say that AI is different this time x402 is only a part, ap2 is the core, payment is available, the question is whether there is a seller, whether the content is an advantage. The last round showed that the AI quality of Web3 is far behind that of Web2, so I don't understand how the extension plugin X402 of Web3 AP2 can dominate the mainstream in AP2 applications Please give me some advice
