leopoldina Fortunati教授在本次访谈中分享了自己关于再生产劳动的独到见解,深入阐释了科技与性别之间错综复杂的相互作用,并对当前中国的一系列发展和现象进行了理论和实践角度的剖析。首先,Fortunati讲述了“爱”的话语、女性主义、家务平分几种话语之间不断演变的动态关系,并提出社会对家务劳动附带的经济价值的认可是解决有关家务劳动和女性之间刻板联系的唯一途径。其次,她从自身最新的研究出发,详细阐述了在再生产领域科技公司利用大语言模型对剩余价值的肆意榨取,以及人工智能如何入侵非物质领域使资本能实现其对劳动力的控制、命令和利润化。同时,她认为一些人工智能产品的设计重新引入了女性被支配的旧社会形象,因此可能会加强女性被支配和轻视的旧意识形态。本文通过对leopoldina Fortunati的访谈,阐释了女性、非物质劳动和技术(尤其是人工智能)之间微妙的关系,并从性别的角度揭示了人工智能可能对整个社会产生的深远影响。

The aim of this presentation is to analyze the relation between mobile phones and globalization. It is the right time to do so,after the long wave of descriptive studies on the practices of use of the mobile phone around the *** fact in these last years we have seen how the spontaneous creation of an area of studies dedicated to the mobile has actually led to the above all phenomenological development of research conducted so far on it(Sandig,Sawhney, Traugott,2004).But,if this was to a certain degree inevitable,and therefore initially justifiable, it must not signal the development of the second stage of studies on the mobile *** is time now to pass to another level that is to challenge the social theory,starting from the analysis of globalization,in order to better understand the social meaning of the mobile *** we try to grasp what is the fundamental tendency of globalization,the principle of fusion appears to be its *** principle of fusion,that is the strengthening of cooperation of labor and integration between the spheres of production and domestic reproduction,emerges as the structural logic of globalization,the paradigm that shows us the direction of most of the social processes taking place in our day.
