Arizona water bills have doubled or tripled in the last year, and a lot of people are pointing fingers at AI and data centers. The viral claim that every ChatGPT prompt uses a full bottle of water has parents, teenagers, and city council members convinced that artificial intelligence is draining the desert dry. But what if the math is completely wrong?

Andy Masley is a former high school physics teacher turned independent researcher who became one of the most cited voices in the national data center conversation after his writing went viral and earned him a private grant from a $4 billion philanthropic organization. He is also the person who caught what may be the single largest factual error ever published in a major bestselling book, a mistake the New York Times covered and the author eventually corrected.

What you will learn in this episode:

• Why the "bottle of water per AI prompt" claim is off by a factor of roughly 500, based on more recent data
• How a missing unit of measurement made a Chilean data center look 1,000 times more water-intensive than it actually was
• What the median ChatGPT prompt actually costs in energy (around 3 watt hours) and how that stacks up against daily life
• Why optimizing AI chip efficiency means each individual prompt is getting cheaper over time, not more expensive
• How Arizona data centers compare to golf courses in water consumption, and which one wins on tax revenue per gallon
• Why focusing on AI water use may be a distraction from agriculture, which accounts for the vast majority of Arizona's water footprint
• What the Loudoun County, Virginia model can teach Arizona cities about negotiating with data centers before they break ground
• How local governments can and should require data centers to internalize infrastructure costs so that burden does not land on ratepayers
• Why noise pollution, not water use, is the issue residents near data centers most consistently raise
• What the recent SRP board election reveals about the tension between clean energy investment and keeping electricity bills low
• Why Andy believes industrial animal agriculture, AI governance, and renewable energy infrastructure are the three highest-leverage issues facing the world right now
