Is AI the Fourth Pillar of Infrastructure? Infrastructure doesn’t go away — it layers. And today, AI is emerging as a new foundational layer alongside compute, storage, and networking. Erik Torenberg interviews a16z’s Martin Casado, Jennifer Li, and Matt Bornstein breaking down how infrastructure is evolving in the age of AI — from models and agents to developer tools and shifting user behavior. We dive into what infra actually means today, how it differs from enterprise, and why software itself is being disrupted. Plus, we explore the rise of technical users as buyers, what makes infra companies defensible, and how past waves — from the cloud to COVID to AI — are reshaping how we build and invest.

My guest is Dr. Chris McCurdy, PhD, FAAPS, professor of medicinal chemistry at the University of Florida and a world expert on the pharmacology of kratom and other plant-derived medicinal compounds. We discuss kratom’s wide-ranging effects, including its use for boosting energy, enhancing mood, managing pain and as a potential opioid substitute, while also explaining its critical safety concerns and addictive potential, especially for kratom-derived/isolate products. We also discuss plant-based compounds more generally for their potential benefits and risks. Dr. McCurdy offers a balanced perspective on kratom and other plant-based and naturally occurring medicinal compounds, highlighting and contrasting their promise for human health with potential serious risks.
