In an open letter, Meta CEO Mark Zuckerberg unveiled the company's vision of "personal superintelligence" for the first time, underscoring the importance of this technology benefiting everyone, not just being controlled by a central entity. He highlighted that while AI systems have already demonstrated the capacity for self-improvement, the advancement towards superintelligence necessitates accelerated efforts. Additionally, to mitigate potential safety risks, Zuckerberg suggested that AI core technology might move towards a closed-source model. He affirmed Meta's commitment to striking a balance between widespread benefits and responsible innovation.
