Ethereum Co-Founder Joseph Lubin Highlights the Risks of AI Control by Major Tech Companies

According to Joseph Lubin, the CEO of Consensys and Co-Founder of Ethereum, the next significant milestone in the crypto space will be driven by artificial intelligence. In a recent interview, Lubin noted that autonomous agents can conduct transactions, coordinate, and verify each other on decentralized networks, leveraging crypto infrastructure for machine-driven activities. He expressed sympathy for the concept that blockchain technology is suited for machine intelligences but emphasized that humans will not be replaced. Instead, increasingly intelligent interfaces will simplify complexity, allowing users to interact with crypto systems through intent rather than manual inputs, with AI serving as an intermediary between people and protocols. However, Lubin warned that if AI infrastructure remains concentrated among a few large tech firms, it could pose significant risks. He stressed the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other in transparent environments. The evolution of products like MetaMask, a Consensys product, reflects this shift. Lubin described MetaMask 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. Lubin also discussed the rise of 'corporate chains' on Ethereum, where companies seek higher throughput and greater control over their infrastructure. He expects assets to be issued on Ethereum's base layer for durability, even if they are used across other networks. Stablecoins, a rapidly growing sector in crypto, are seen as a stepping stone toward more decentralized financial systems. Lubin noted that current models rely heavily on centralized issuers but expects growth in decentralized collateral to enable more robust, crypto-native forms of money. On tokenization, Lubin suggested that traditional finance and decentralized finance are converging, combining centuries of financial innovation with newer blockchain-based systems. This convergence will result in a more granular and programmable global economy. Regarding longer-term technical risks like quantum computing, Lubin adopted a measured tone, stating that Ethereum developers have been preparing for years and see it as part of the natural evolution of Ethereum.
