"While AI investment thus far has been focused on model development, a substantially larger hardware and software push will likely be required for generative AI to scale," Briggs and Kodnani wrote.Even as AI investment is projected to ramp up dramatically in the next few years, it would still only represent a small percentage of U.S. and global economic output.
"Despite this extremely fast growth, the near-term GDP impact is likely to be fairly modest given that AI-related investment currently accounts for a very low share of U.S. and global GDP," the authors wrote.
