Given this, America’s declining productivity growth – which has averaged just 0.7% annually since 2010 – has led some observers to blame the slowdown on inadequate technological advances. These pessimists, such as the economist Robert Gordon, claim that new innovations are unlikely to improve productivity as fundamentally as electricity, automobiles, and computers did in the last century.
在这一前提下，美国的生产力增长放缓——自2010年以来年均仅增长0.7%——令某些观察家将这一放缓归罪于科技进步过慢。这些悲观主义者，比如经济学家罗伯特·戈登（Robert Gordon）都认为新的科技创新都不可能像上世纪的电力，汽车和计算机那样为生产力带来翻天覆地的变化。
