Applying the lens of computation and information has been instrumental in driving the technological progress of our civilization as well as in empowering our understanding of the world around us. The digital computer was and for many still is the leading metaphor for how our mind operates. Information theory (IT) has also been important in our understanding of how nervous systems encode and process information. The target article deploys information and computation to bodies: to understand why they have evolved in particular ways (animal bodies) and to design optimal bodies (robots). In this commentary, I argue that the main role of bodies is not to compute.

翻译：应用计算与信息的视角，不仅推动了人类文明的技术进步，也深化了我们对世界的理解。数字计算机曾经（且对许多人而言至今仍是）解释心智运作的主导隐喻。信息论在理解神经系统如何编码与处理信息方面亦发挥了重要作用。目标论文将信息与计算的概念延伸至身体：旨在理解动物身体为何以特定方式演化，并指导机器人身体的优化设计。本文评述认为，身体的主要功能并非计算。
