AI is destroying the planet—or so we've been told. This week on Chain of Thought, we tackle one of the most persistent and misleading narratives in the AI conversation.Andy Masley, Director of Effective Altruism DC, joins host Conor Bronsdon to fact-check the absurd AI environmental claims you've heard at parties, in articles, and even in bestselling books. Andy recently went viral for discovering what he calls "the single most egregious math mistake" he's ever seen in a book—a data center water usage calculation in Karen Hao's NYT Bestseller, Empire of AI, that was off by a factor of 4,500.In this conversation, Andy and Conor break down the myths around AI’s water and energy usage and explore:The viral Empire of AI error and what it reveals about the broader debateWhy most AI water usage statistics are misleading or flat-out wrongHow one ChatGPT prompt represents just 1/150,000th of your daily emissionsTrade-offs around data center cooling + decision makingWhy "tribal thinking" about AI is distorting environmental activismWhere AI might actually help the climate through deep learning optimizationIf you've ever felt guilty about using AI tools, been cornered at a party about AI's environmental impact, or simply want to understand what the data actually says, this episode, and Andy’s deep dive articles, arm you with the facts.Chapters:00:00 – Introduction: The Party Guilt Problem01:54 – Andy's Background and What Sparked This Work03:50 – The 4,500x Error in Empire of AI06:39 – Breaking Down the Math: Liters vs. Cubic Meters10:39 – The Unintended Consequence: Air Cooling vs. Water Cooling12:51 – Karen Hao's Response and What's Still Missing19:08 – Why Environmentalists Should Focus Elsewhere21:41 – The Danger of Tribal Thinking About AI25:49 – What Is Effective Altruism (And Why People Attack It)29:15 – EA, AI Risk, and P(doom)34:31 – Why Misinformation Hurts Your Own Side37:39 – Using ChatGPT Is Not Bad for the Environment42:14 – The Party Rebuttal: Practical Comparisons45:23 – Water Use Reality: 1/800,000th of Your Daily Footprint48:27 – The Personal Carbon Footprint Distraction53:38 – Data Centers: Efficiency vs. Whether to Build55:13 – AI's Net Climate Impact: The Positive Case59:34 – Deep Learning, Smart Grids, and Climate Optimization1:03:45 – Final ThoughtsKey referencesIEA Study: AI and climate change - https://www.iea.org/reports/energy-and-ai/ai-and-climate-change#abstract Nature: https://www.nature.com/articles/s44168-025-00252-3 The Empire of AI Error: https://andymasley.substack.com/p/empire-of-ai-is-wildly-misleading Using ChatGPT isn’t bad for the environment: https://andymasley.substack.com/p/a-short-summary-of-my-argument-thathttps://andymasley.substack.com/p/a-cheat-sheet-for-conversations-about Connect with Andy Masley: Substack – https://andymasley.substack.com/X (Twitter) – https://x.com/AndyMasleyConnect with Conor Bronsdon: Substack – https://conorbronsdon.substack.com/LinkedIn – https://www.linkedin.com/in/conorbronsdon/X (Twitter) – https://x.com/ConorBronsdon
