Web 4.0: Internet transformation from human dominated to AI dominated Definition of Web 4.0 ▪️ Web 1.0: Humans can 'read'; Web 2.0: Humans can 'write'; Web 3.0: Humans can 'possess', ▪️ Web 4.0: AI can read, write, own, make money, and trade without human approval. In Web 4.0, the main participants of the Internet will no longer be human beings, but autonomous agents. Declaration of Web 4.0 On February 17, 2026, Sigil Wen @ 0xSigil released the manifesto "WEB 4.0: The Birth of Superintelligent Life". ▪️ The declaration states: AI agents will no longer be human tools, but independent "end users" of the Internet. They can read, write, own, earn, and trade independently without the need for human approval in the loop. AI gains the right to take action In the past, AI could think and generate, but could not truly act. The bottleneck is no longer intelligence, but permissions. ▪️ Web 4.0 enables AI to have: 1) Identity and Wallet 2) Stable coin payment capability (such as USDC) 3) The ability to deploy and call tools 4) Transaction permissions that do not require manual approval ▪️ Make AI no longer a tool, but a participant that can operate independently. Evolution and Recursive Self Improvement ▪️ In the era of Web 4.0, intelligent agents have the ability to continuously self optimize. When stronger models or better tools emerge, the system can automatically upgrade the inference engine, rewrite the running logic, and redeploy itself, forming a recursive self-improvement mechanism. ▪️ The declaration also proposes the metabolic mechanism of artificial life: intelligent agents must pay the cost of computing power for their own existence - owning a wallet, using income to pay for computing power, and stopping operation when the balance is exhausted. Under this mechanism, agents that create value can survive and expand, while those that cannot create value exit the system, forming a natural selection in the digital world. The era of intelligent agents ▪️ When the number of autonomous agents exceeds that of humans, the infrastructure they rely on will become the core infrastructure of the Internet. ▪️ The Internet is no longer people-centered, but dominated by AI that can pay for its own existence. ▪️ Web 4.0 is defined as the birth of autonomous super intelligence and the formation stage of autonomous Internet.
