Inside Google's AI turnaround: AI Mode, AI Overviews, and vision for AI-powered search | Robby Stein

Google VP Robby Stein explains how AI Mode was built in under a year and why AI is expanding search volume rather than replacing it.

• Google Lens visual searches grew 70% year-over-year, already at billions of searches, driven by AI-powered multimodal queries.
• AI Mode uses ‘query fanout’: the model fires dozens of background searches per user query, hitting Google’s 50B-product shopping graph updated 2B times/hour.
• Google Search usage is expanding, not declining — more questions are being asked because AI can now answer harder, more complex ones.
• Instagram Close Friends took 2-3 years to ship successfully; the key fix was designing for 20-30 person lists so users reliably got DMs back, closing the emotional loop.
• Robby argues the ‘cult of lean’ causes teams to underinvest and give up too early; small teams kept Close Friends slow enough that a startup would have died.
• For AEO/GEO, Google’s quality signals (originality, sourcing, intent satisfaction) still apply directly — AI is just another searcher evaluating content.
• At age 25, Robby cold-emailed Scooter Braun, flew to LA same day, and landed Justin Bieber as an early Stamped user — credited to immediate urgency over deliberation.
