Warren Buffett says AI investment is not a bubble, calls it real money

Berkshire Hathaway Chairman Warren Buffett said big tech companies\' large-scale investment in artificial intelligence facilities should not be seen as a simple bubble, calling it long-term infrastructure buildout. He likened the scale of current AI spending to 19th century U.S. railroad construction and said it involved \"real money\". The article cites forecasts that AI spending by Meta, Microsoft, Amazon and Alphabet could reach up to $750 billion this year and up to $4.5 trillion in 2030.
