Ethereum Co-Founder Warns of AI Control Risks by Major Tech Companies

The next significant milestone in the crypto space is expected to be driven by advancements in artificial intelligence, according to Joseph Lubin, CEO of Consensys and co-founder of Ethereum. In a recent interview, Lubin highlighted the potential of autonomous agents to facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure as the foundation for machine-driven activities. He expressed support for the idea that blockchain technology is particularly suited for machine intelligences but does not envision humans being replaced. Instead, he believes that increasingly sophisticated interfaces will simplify complexities, enabling users to interact with crypto systems through intent rather than manual inputs, with AI serving as an intermediary layer between people and protocols. However, Lubin cautioned that if AI infrastructure remains under the control of a few large tech firms, it could pose significant risks. He emphasized the importance of decentralized systems and cryptography in ensuring accountability and enabling transparent, verifiable environments where machines can 'check on one another'. Products like MetaMask are being revamped to reflect this shift, with Lubin describing it as a 'new kind of neobank that you own and control', part of a transition toward a 'personal money operating system'. AI-powered agents could manage assets, execute transactions, and navigate the growing decentralized economy on behalf of users. The rise of 'corporate chains' on Ethereum is another significant trend, with Lubin expecting companies to seek higher throughput and greater control over their infrastructure. He advised that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are seen as a stepping stone toward more fully decentralized financial systems, and Lubin anticipates growth in decentralized collateral to enable more robust forms of crypto-native money. On tokenization, he suggested that traditional finance and decentralized finance are converging, combining financial innovation with blockchain-based systems to create a more granular and programmable global economy. While acknowledging the potential risks of quantum computing, Lubin adopted a measured tone, stating that Ethereum developers have been preparing for this eventuality for years and see it as part of the natural evolution of Ethereum.
