I cannot read the paper that this article is based on, but it seems that it refers to the use of big data analytics and AI in 2024, not LLM. It concludes that the use of AI leads to a 4% increase in productivity. Nowadays the debate over AI productivity centers around LLMs, not big data analytics. This article does not seem to contradict more recent findings that LLM do not (yet) provide any increased productivity at the company level.
