Bank of Korea: AI saves 1 hour/week but zero productivity gain
South Korea's central bank finds AI doesn't boost profitability—despite massive investment.
The Bank of Korea, a credible source from the country profiting most from the AI boom via semiconductor sales, released a report analyzing AI's impact on workplace productivity. The headline finding: using AI saves workers about 1 hour per week (3.8% of workload). However, that saved time doesn't lead to higher output for the company. Instead, AI accelerates report-writing, leading to more reports and review cycles—effectively expanding administrative work rather than freeing up capacity. Even if workflows were perfectly optimized without these side effects, the report estimates real productivity gains would max out at only 1%.
This stark assessment challenges the prevailing narrative that AI will dramatically boost economic productivity. The report notes that the time saved is not monetized for workers (no extra pay) and that the total volume of work increases at the company level. For context, South Korea—home to Samsung and SK Hynix—has seen enormous investment in AI hardware, yet the actual productivity benefit appears negligible. The report suggests that AI's promise of efficiency may be inflated, with real gains far smaller than the hundreds of billions spent on development. For businesses and policymakers, this raises critical questions about AI's return on investment and whether the technology is truly transforming work or just adding complexity.
- AI saves 1 hour per week per worker (3.8% time reduction), according to the Bank of Korea.
- Time saved does not increase profitability; workers produce more reports, boosting administrative overhead.
- Maximum estimated productivity gain under ideal conditions is only 1%, despite massive GPU/chip investments.
