Excerpt: "The AI money trap
"We don’t have to look far for a more contrarian perspective. Economist Paul Kedrosky, for one, notes that capital expenditure on data centers has driven 1.2% of national GDP, acting as a kind of stimulus program. Without that investment, he writes, the US economy would be in contraction.
"Kedrosky describes an 'AI #datacenter spending program' that is 'already larger than peak telecom spending (as a percentage of GDP) during the dot-com era, and within shouting distance of peak 19th century railroad infrastructure spending.'
"Virtually all #AI spend flows into #Nvidia in one way or another. This is reflected in its recent valuation as the first publicly traded company to break $4 trillion in market capitalization (second up was #Microsoft).
"To put that number in context, market observers such as Forbes described it as being greater than the GDP of Canada or the annual global spending on defense.
"Nvidia alone accounts for more than 7% of the value of the S&P 500. AI gadfly Ed Zitron calls it the 'AI money trap.' "
