Debunking AI's Environmental Panic | Andy Masley

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 debate

• Why most AI water usage statistics are misleading or flat-out wrong

• How one ChatGPT prompt represents just 1/150,000th of your daily emissions

• Trade-offs around data center cooling + decision making

• Why "tribal thinking" about AI is distorting environmental activism

• Where AI might actually help the climate through deep learning optimization

If 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.
