这篇由耶鲁大学预算实验室执行长Martha Gimbel撰写的文章探讨了人工智慧能否帮助美国应对人口老化与出生率下降带来的经济挑战。美国国会预算办公室预测,自2031年起年死亡人数将超过年出生人数,到2055年生育率将降至每名女性1.5个孩子。尽管有观点认为AI可以填补劳动力缺口、提升生产力并照顾老年人,但作者认为这两大转型在短期内更可能相互加剧,而非相互抵消,进一步削弱劳动市场的稳定性。

文章指出,AI能胜任的工作与老龄化社会最需要的工作之间并无明显对应关系。例如,航空或船舶上的乘客服务员拥有较高龄的劳动力,但不太可能被AI取代;医疗转录员则高度暴露于AI替代风险中,但该职业的老年从业者比例并不高。此外,年轻工人通常更容易适应新技术和职业转型,而人口老化意味著经济体中最具适应力的劳动者将越来越少,这使得劳动力市场的灵活调整更加困难。

作者以工业革命为类比,提醒人们技术变革的过渡期往往充满痛苦与动荡。虽然工业革命最终提升了生活水准,但经历那段时期的人们承受了巨大的压力与苦难。经济史学家Mokyr的研究显示,工业革命若非伴随著快速的人口增长,其对收入的正面影响可能会更快显现。然而作者认为,当前人口趋势反向发展并不意味著AI转型会更顺利,因为AI的能力与老龄社会的需求并不匹配,美国经济将不得不同时应对两场巨大的转型,且彼此会使对方更加复杂。

This Bloomberg essay by Martha Gimbel, co-founder of the Budget Lab at Yale, examines whether artificial intelligence can counteract the economic slowdown caused by America's aging population and declining birth rate. The Congressional Budget Office projects that deaths will surpass births by 2031 and fertility will drop to 1.5 births per woman by 2055. While some optimists argue AI could fill labor gaps and boost productivity, Gimbel contends that the convergence of demographic decline and AI-driven disruption is more likely to compound labor market instability in the near term rather than produce a convenient offset.

A central argument of the article is that there is little correlation between jobs held predominantly by older workers and those most susceptible to AI automation. Passenger attendants have aging workforces but low AI exposure, while medical transcriptionists face high AI displacement risk yet skew younger. This mismatch means AI will not simply fill the vacancies left by retiring workers. Furthermore, retraining and career transitions are notoriously difficult, as demonstrated by the China trade shock, and an aging workforce has fewer of its most adaptable — younger — workers to navigate such shifts.

Gimbel draws on the Industrial Revolution as a cautionary parallel, noting that while it ultimately raised living standards, the transition itself was disruptive, violent, and deeply painful for many. Economist Joel Mokyr's research suggests that rapid population growth during that era worsened the adjustment period. However, Gimbel argues that the current opposite demographic trend will not necessarily make the AI transition smoother, because the skills AI can provide and the labor needs of an aging society are fundamentally misaligned. The most probable outcome is that the US economy will face two massive, simultaneous transitions that complicate each other rather than cancel out.
