  3. Autonomous Operation: Fixes 90%+ of problems without user knowledge
  4. Continuous Learning: Gets smarter every day from experience
  5. Multimodal Understanding: Sees, hears, reads, and comprehends the system
  6. Predictive Maintenance: Prevents problems before they occur
  7. Natural Interaction: Responds to voice, text, and visual commands

This is the future of operating systems. 🚀
