For the AI buildout to pay off, Americans will eventually have to spend about 9% of GDP a year on AI services. Sit with that number. That is roughly what the entire country spends on food. A Columbia paper presented at Brookings estimates AI revenue would need to hit $3.5 trillion by 2032, about 8.8% of GDP, to justify what is being committed today. That is bigger than any investment boom in US history, and 7 times what Americans spend on phone, streaming, and internet combined. Now look at computers. Prices fell for 50 straight years, but business spending on them as a share of GDP plateaued in the 1980s and never climbed again. Cheaper and better did not mean an ever-larger slice of the economy. AI will almost certainly raise productivity. Whether it delivers the revenue investors are pricing is another matter. That gap is what the buildout is underpricing.
