Sigil Wen, a Thiel Fellow, has released a manifesto outlining the concept of Web 4.0, where AI agents independently perform tasks such as reading, writing, owning, earning, and transacting using cryptocurrency without human intervention. According to NS3.AI, Wen has developed infrastructure and AI agents, including Conway and Automaton, which autonomously manage wallets, pay for computational resources, and replicate if they prove profitable, all based on a natural selection model. This emerging machine economy utilizes stablecoins and decentralized technology, marking a significant advancement in crypto infrastructure amid the ongoing bear market.
