TL;DR
AI systems are becoming much better at specific, limited tasks, but they still struggle with complex, long-term projects and require human help for high-stakes decisions. Simply adding AI to a human workflow doesn't automatically boost performance, and can even hurt if the human isn't skilled at checking the AI's work. To keep up, education and professional training must stop just teaching content and start teaching the critical skill of verifying AI-generated output.
Method and sample: The paper provides a review and synthesis of multiple large-scale datasets and meta-analyses, including the 106-experiment meta-analysis by Vaccaro et al. (2024), human-AI productivity studies (e.g., Brynjolfsson et al., 2025; Noy & Zhang, 2023), and benchmark performance data from METR, Stanford AI Index, and GPQA evaluations involving expert human baselines.
