At least this era left a legacy of efficient search engines and a fiber-optic infrastructure. But it is not an easy matter to assess how the time savings implied by online shopping, or the cost savings that might result from increased competition (owing to greater ease of price comparison online), affects our standard of living.
类似地，前一次互联网泡沫也打着创新的幌子，尽是些可以让你在线订购狗粮和软饮料的网站。这次创新潮好歹还留下了管用的搜索引擎和光纤基础设施。但很难说在线购物所节省的时间，或者竞争的提高（因为上网比较价格比以前方便了很多）所节省的成本在多大程度上影响了我们的生活水平。
