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

The next significant turning point in the crypto space is expected to come from advancements in artificial intelligence, according to Joseph Lubin, CEO of Consensys and Ethereum co-founder. In a recent interview, Lubin stated that autonomous agents can engage in transactions and verification on decentralized networks, utilizing crypto as the foundation for machine-driven activities. He expressed sympathy for the idea that blockchain technology is suited for machine intelligences but emphasized that humans will not be replaced. Instead, increasingly sophisticated interfaces will simplify complexity, enabling users to interact with crypto systems through intent rather than manual inputs, with AI serving as the intermediary layer between people and protocols. However, Lubin warned that if AI infrastructure remains concentrated among a few large tech companies, it could pose significant risks. He stressed the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other's actions in transparent environments. Products like MetaMask are evolving 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 decentralized economy on behalf of users. Lubin also pointed to structural changes in the Ethereum ecosystem, including the rise of corporate chains, which are expected to become more common as companies seek higher throughput and greater control over their infrastructure. He emphasized that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are seen as a stepping stone toward more decentralized financial systems, and tokenization is expected to lead to a more granular and programmable global economy. While Lubin acknowledged the potential risks of quantum computing, he struck a measured tone, stating that Ethereum developers have been preparing for this eventuality and see it as part of the natural evolution of the Ethereum network.
