Chris Dixon, founder and managing partner of a16z crypto, discussed the impact of AI and blockchain on the Internet. He noted that AI is disrupting the current Internet economic model, enhancing the power of large tech companies, and eroding user trust through deep fakes and fake accounts. In contrast, blockchain offers a way for users to regain control by providing decentralized solutions and transparent, tamper-proof mechanisms. Blockchain can enhance digital asset ownership, verify identities to eliminate fake accounts, and improve content authenticity and security. The combination of AI and blockchain could keep the Internet open, diverse, and innovative, addressing AI-related challenges while preserving its core principles.
