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

The cryptocurrency space is on the cusp of a significant transformation driven by artificial intelligence, according to Joseph Lubin, CEO of Consensys and co-founder of Ethereum. In a recent interview, Lubin emphasized the potential of autonomous or semi-autonomous agents to interact, coordinate, and verify transactions on decentralized networks, leveraging crypto infrastructure as a foundation for machine-driven activities. He expressed support for the idea that blockchain technology is suited for machine intelligences but clarified that he does not envision humans being replaced. Instead, increasingly sophisticated interfaces will simplify complexity, allowing users to engage 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 concentrated among a few large technology companies, it could pose significant risks. He stressed the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to operate transparently and verifiably. The evolution of products like MetaMask, a Consensys offering, reflects this shift. Lubin described the wallet as being rebuilt into a 'new kind of neobank that you own and control,' part of a transition toward a 'personal money operating system.' AI-powered agents could act on behalf of users, managing assets and executing transactions within a growing decentralized economy. Lubin also pointed to structural changes in the Ethereum ecosystem, including the rise of 'corporate chains' as companies seek higher throughput and greater control over their infrastructure. While he expects assets to be best issued on Ethereum's base layer for durability, he noted that stablecoins are part of a broader transition toward more fully decentralized financial systems. Stablecoins, however, are seen as a 'stepping stone' rather than the endpoint, as they currently rely heavily on centralized issuers. Over time, Lubin anticipates growth in decentralized collateral, enabling more robust forms of crypto-native money. On tokenization, he suggested that traditional finance and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems to create a more granular and programmable global economy. Despite these shifts, Lubin downplayed the immediate risks associated with quantum computing, stating that Ethereum developers have been preparing for this challenge as part of the platform's natural evolution.
