Elon Musk Compares AI Infrastructure Spending to Global Economic Scale

Tesla and SpaceX CEO Elon Musk argued that Earth's economy is small compared to a potential "K2 economy" while sharing a chart on AI infrastructure spending. The data, attributed to Columbia Business School professor Stijn Van Nieuwerburgh, projects AI outlays to average 3.63% of GDP between 2025 and 2032, surpassing historical infrastructure booms like railroads and telecommunications. While some experts warn of potential bubbles and risks to lenders, Musk emphasized the Kardashev scale to highlight the vast energy potential of advanced civilizations.
