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

The next significant milestone in the crypto space is expected to emerge from advancements in artificial intelligence, according to Joseph Lubin, CEO of Consensys and co-founder of Ethereum. In a recent conversation with CoinDesk, Lubin emphasized that autonomous agents can facilitate transactions, coordination, and verification on decentralized networks, leveraging crypto infrastructure as the foundation for machine-driven activities. Lubin, who is set to speak at Consensus Miami 2026, expressed his support for the idea that blockchain technology is particularly suited for machine intelligences but does not foresee humans being replaced. Instead, he envisions increasingly intelligent interfaces simplifying complexity, allowing users to interact with crypto systems through intent rather than manual inputs, with AI serving as the intermediary layer between people and protocols. However, this vision also comes with potential risks, particularly if AI infrastructure remains concentrated among a few large tech firms, which could lead to significant troubles, as warned by Lubin. He stressed the importance of decentralized systems and cryptography in ensuring accountability and enabling machines to verify each other in transparent environments. Products like MetaMask are evolving to reflect this shift, with Lubin describing the wallet as a new kind of neobank that users 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 emphasized that assets are best issued on Ethereum's base layer to ensure durability. Stablecoins are part of this transition but are seen as a stepping stone toward more fully decentralized financial systems. Tokenization is expected to bring about a convergence of traditional and decentralized finance, resulting in a more granular and programmable global economy. Lubin also addressed concerns about quantum computing, adopting a measured tone and stating that Ethereum developers have been preparing for this potential risk over the years.
