News Feed as Major Invention

Shaan Puri believes the algorithmic news feed represents one of the most significant technological shifts of the past two decades. He argues that if someone time-traveled from 2006 to today, the personalized content delivery system would be one of the most striking changes they'd notice.

Key Points:

• The Shift from Mass to Personal:

  • 20 years ago, content needed mass appeal (newspapers delivered the same content to everyone)
  • Today's algorithms (TikTok, Instagram, Facebook) deliver highly personalized content
  • Instead of "a little something for everybody," it's now "a hell of a lot just for you"

• Mass Personalization as a Theme:

  • This is one of the two big themes for AI in 2026
  • The trend extends beyond social media into all aspects of digital experience
  • Everyone is now looking at completely different content on their phones, tailored specifically to them

• The Observable Change:

  • Not only is everyone on their phone (a tiny computer)
  • But what they're looking at is fundamentally different from person to person
  • This represents a complete departure from the shared media experiences of the past (like everyone watching TRL after school)

• AI's Role in Acceleration:

  • AI enables even deeper personalization beyond what current algorithms provide
  • The technology can create feedback loops that make systems smarter over time
  • Personal preferences and patterns can be remembered and applied across different use cases
