Computing accelerators must significantly improve at least one metric such as: cost, speed, or efficiency for customers to find them useful. They must do this for at least one application that large numbers of users care about to become a commercial success. Furthermore, accelerators must improve the metric that customers care most about for a given application. We show that it is trivial to build an embedded sensor system that improves temperature sampling speed by 38,142 times and energy efficiency by 2 times compared to the state of the art in an application where these metrics do not matter. We then explain that this computing accelerator is not likely to displace the bimetallic kettle switch in the market because consumers are optimizing for cost, not temperature measurement sampling speed and efficiency when they buy a kettle.

翻译：计算加速器必须在至少一项指标（如：成本、速度或效率）上有显著提高，以使客户认为它们有用。它们必须至少对一个大量用户关心的应用程序进行改进，才能成为商业成功。此外，加速器必须改善客户在给定应用程序中最关心的指标。我们展示了在一种不重视这些指标的应用程序中，轻松构建嵌入式传感器系统可以将温度采样速度提高38,142倍，将能量效率提高2倍。我们随后解释了这款计算加速器不太可能在市场上取代双金属水壶开关，因为消费者购买水壶时优化的是成本而不是温度测量采样速度和效率。
