So are we in an AI bubble? Here are clues to look for.

🎙️ The Speakers & Context

• The Format: Host-led discussion with expert interviews.
• The Key Players:
  • Hosts: Nick Fountain and Jeff Guo (Planet Money NPR), blending journalism with economic storytelling; their angle is accessible bubble analysis amid AI hype.
  • Guests: Robin Greenwood (Harvard Business School professor), bubble detection expert via historical data; Gotti Barlevi (Chicago Fed senior economist), macro impacts specialist.
• The Vibe: Investigative and playful, demystifying economics with humor (e.g., Labubu dolls, ankle socks) while probing serious risks.

🎣 The Executive Hook

• The "One Big Idea": AI's stock surge shows early bubble signals (high valuations, volatility) but lacks full predictors like issuance or acceleration, suggesting it's not yet a catastrophic pop waiting to happen. Bubbles in innovative tech may overfund R&D externalities, turning "wasted" capex into infrastructure like dot-com's dark fiber that later enabled broadband.
• Why It Matters: In a low-rate, AI-accelerated economy, distinguishing productive bubbles from destructive ones guides capital flows; policymakers face lean vs. clean choices as AI capex rivals housing bubble scale, potentially amplifying recessions or boosting productivity.
