The personal and broader use cases Zuckerberg lists for 'personal superintelligence'
AI-generated writing.
Zuckerberg’s letter mixes his own household examples with the broader categories Meta is building toward. His personal examples: his agent flags interesting information and helps prototype ideas, monitors his sleep and gives feedback as he trains, and plans personalized recipes with his 8-year-old daughter — ordering ingredients and offering suggestions as they bake. That same daughter also codes her own ideas and produces videos in an evening (work he says would have taken him months or been impossible before), and the two of them are now designing a robot together.
The broader categories he lists for everyone:
- Personal agent — works 24/7 on relationships, health, career, finances, home management, and hobbies, with privacy strong enough (he compares it to WhatsApp-style encryption) that no one else, including Meta, can access it.
- Creation tools — beyond his daughter’s example, he cites Meta researchers generating novel crystal structures for AR glasses and engineers building new apps in a fraction of the previous time.
- Business tools — letting people manifest ideas without raising money or building large teams, which he predicts leads to more businesses and, over time, more employment rather than less.
- Tutor/coach — a “PhD in every subject” with unlimited patience, aimed at giving students the help currently only available to those whose parents can pay, and adults a way to learn new job skills, languages, or hobbies.
- Scientific advances — Biohub’s open source biological models (virtual cells, proteins) helping design new drugs, plus personalized therapies and faster trials enabled by people’s direct involvement.
- Free or affordable access — free tiers for billions of people, and a dynamic auction mechanism for paid compute meant to guarantee the lowest price for whatever capacity people collectively value most.
He also uses two thought experiments to argue for wide distribution over concentration: a superintelligent lawyer available to only one person creates unfair advantage in court, but available to everyone makes justice more fair and efficient; cybersecurity superintelligence held by one actor could break into almost any system, but distributed widely it hardens every system instead.
