Harvard economist warns data centers mask weak US GDP growth

US GDP growth in the first half of 2025 was only 0.1% without data center investments, according to Harvard economist Jason Furman. This tech boom, driven by major companies like Microsoft and Amazon, accounted for 92% of the nation's GDP expansion, masking weakness in other sectors. While non-tech sectors like manufacturing and real estate are struggling, economists remain puzzled by the overall strong GDP figures despite slowing job growth.
