如今，人工智能的发展面临着重重阻碍：新建数据中心的计划被叫停，人们担忧人工智能会导致失业，对其安全性也日益担忧。
The walls are closing in on artificial intelligence: moratoriums on new data center construction, job-loss concerns and rising alarm over safety.
这些担忧都合情合理。然而，这些因素都不足以让我们放弃这项历史上最具革命性的技术之一。人工智能有望重振增长乏力的经济，帮助我们解决国家面临的诸多棘手难题。尽管存在诸多顾虑，我们依然需要人工智能来推动发展。
All valid worries. But none are sufficient to turn away from one of the greatest technological innovations in history, one with the potential to reinvigorate our slow-growth economy and make it easier to address the country’s increasingly challenging problems. For all the concern about the technology, we need A.I. to deliver.
简单回顾一下经济学基础知识：经济增长以及随之而来的收入与生活水平提升，取决于两个因素——劳动力规模的扩大以及每个劳动者的生产效率。劳动力人数增加能扩大经济总量，但只有每个劳动者的产出提高，个人才能从中获益。
A quick Economics 101 refresh: Growth — and the increases in incomes and living standards that come with it — is a function of just two things, a larger labor force and how much each worker produces. More workers increase the overall size of the pie. But individuals don’t get a larger share unless each worker produces more.
国家收入的增加，尤其是源于生产效率提升带来的收入增长，能让国家更有能力实现财富公平分配、缩小贫富差距。同时，这也能为控制国家债务、提供医疗与教育等公共服务提供资金保障。
Greater national income, particularly if it comes from higher productivity, gives the nation more legroom to redistribute wealth fairly among citizens and reduce inequality. It also provides resources to hold down the national debt and fund public services such as health care and education.
