日常实践中边界的概念是重要的，不仅决定了日常活动开展的资源划分，还塑造了社会世界的发展轨迹。本文讨论的问题是当边界被镌刻于算法之上时，边界的实质是什么？程序员如何嵌入到算法实践中去生产边界？研究认为，算法程序员作为“技术专家”追求流程的无可争议性、工具模型的有效性、技术认知的连贯性，“技术天才”的集体身份是他们对技术和组织做出的某种深刻承诺，由此建立的社会边界扩大了程序员的技术权威性。然而，程序员的技术感受并非建立在乌托邦意义上，而是建立在物质报酬基础上，企业组织通过财富允诺鼓励技术人员日复一日、充满激情地付出，而不计较自我价值的快速贬损。算法程序员将自我能力和职业身份的描述化约为对数据指标和模型的优化，臣服于标准化的组织实践，不加批评地获取鲜活的用户体验，“技术天才”并没有成为社会判断力的正义使者，仿佛算法机器中的一颗齿轮。当有一天，他们的价值被组织拾取殆尽，便成了技术社会大分工中剩余类别的一种。被裁的程序员要重新进入社会寻找岗位，这并非是个人所想要追求的流动，而是被迫在社会竞争中被重新定价和排序。集体的技术聚合并没有产生额外的个人活力，边界工作与边界对象成为一个逆向过程（reverse process）。

In everyday practice, the concept of boundaries is important, as it not only determines the allocation of resources for daily activities but also shapes the development trajectory of the social world. This paper addresses the issue of what constitutes the essence of boundaries when they are inscribed within algorithms. How do programmers engage with algorithmic practices to define and produce these boundaries? The research argues that algorithm programmers, as “technical experts”, pursue the indisputability of processes, the efficacy of tool models, and the coherence of technical cognition. The collective identity of “technical genius” represents a profound commitment that they make to both technology and organization, thereby expanding the technical authority of programmers through the establishment of social boundaries. However, programmers, technical perceptions are grounded not in a utopian foundation but rather on material rewards. Corporations encourage the passionate daily contributions of technical personnel through promises of wealth, ofen overlooking the rapid devaluation of their self-worth. Algorithm programmers reduce the expression of their skills and professional identity to the optimization of data metrics and models, conforming to standardized organizational practices and uncritically adopting vibrant user experiences. The “technical geniuses” do not become just arbiters of societal judgment, akin to cogs in the machine of algorithms. When their value is eventually depleted by the organization, they become a surplus category in the grand division of labor in technology. Laid-off programmers have to re-enter society to find positions, a mobility not personally desired but forced by the need to be revalued and ranked amid social competition. The collective technical aggregation fails to generate additional individual vitality. The boundary work and boundary objects undergo a process of reversal.
