身体不是为了计算而存在，而是为行动与适应服务。
The body is not there to compute: Comment on "Informational embodiment: Computational role of information structure in codes and robots" by Pitti et al
- 反对将身体视为信息处理器，强调其行动与环境互动功能
- 指出动物与机器人设计中过度依赖计算模型的误区
- 适合关注具身智能、认知科学与机器人学交叉领域的研究者
以计算与信息为视角，推动了文明的技术进步，并深化了我们对世界的理解。数字计算机长期以来被视为心智运作的主导隐喻。信息论（IT）也帮助我们理解神经系统如何编码与处理信息。目标文章运用信息与计算概念来解释身体为何以特定方式演化（动物身体），以及如何设计最优身体（机器人）。本文评论则主张：身体的主要功能并非计算，而是服务于行动与环境交互。
原文摘要 · Abstract (English)
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.
