所有AI的馈赠，早已在暗中标好了价格｜北大最新论文解读

Core Insights - Generative AI is reshaping various industries and fundamentally altering human writing, cognition, and thinking processes, with initial optimism suggesting it could lead to "work equity" [4] - However, recent studies indicate that generative AI is reinforcing a "seniority bias" in the labor market, exacerbating inequality rather than alleviating it [7][9] Group 1: Impact on Labor Market - A study analyzing employment data from 2015 to 2025 revealed that while entry-level and senior positions grew at similar rates until 2022, a divergence began in 2023, with entry-level positions declining by 7.7% in AI-adopting companies, while senior roles remained stable or slightly increased [9] - The CEO of Ctrip commented that AI is likely to replace entry-level intellectual labor, worsening challenges faced by younger individuals in education, marriage, and early career stages [9] Group 2: Effects on Knowledge Production - A large-scale natural experiment analyzed over 419,000 academic papers across 21 disciplines before and after the release of ChatGPT-3.5, revealing a dual effect: while knowledge production accelerated, content homogeneity also increased significantly [10][15][16] - Post-release, the average annual publication per scholar increased by 0.9 papers, and the quality of journals improved by 6%, particularly in technical and physical sciences [21] Group 3: Long-term Cognitive Effects - A follow-up longitudinal study indicated that while AI usage temporarily boosts creativity, this effect diminishes once AI assistance is removed, suggesting that the enhancement is not sustainable [42] - The study found that participants who relied on AI exhibited a significant increase in content similarity and language style homogeneity, indicating a long-lasting "creative scar" [39][42] Group 4: Recommendations for Individuals - To mitigate the cognitive impact of AI, individuals are encouraged to use AI as a "thought partner," engage in deliberate cognitive friction by questioning AI outputs, and establish "no-AI time" to maintain independent thinking skills [50]
