Mark Zuckerberg published a 6,500-word essay proposing "personal superintelligence"—AI distributed widely and privately controlled by individuals rather than concentrated in corporate or government hands. This directly challenges competitors like OpenAI and Anthropic's strategy of positioning themselves as trusted safety guardians. However, critics note Meta's credibility gap: while the core decentralization concept is philosophically sound, Meta's ongoing legal battles over social harm to minors and data privacy undermine its pitch to billions of users for personal AI access in health, finance, and relationships. The article underscores a key tech debate: whether vision alone suffices without institutional trust.
