Tech Ethics Crisis: Are Big Tech Companies Doing Good?

2024-12-29

Moshe Y. Vardi, a professor at Rice University, revisits his previous stance on the tech ethics crisis. Initially believing that laws and regulations were sufficient to address computing's negative impacts, he now argues that a genuine ethical crisis exists, given the growing power of tech corporations and the ethical issues inherent in their business models. He questions the ethics of working for Big Tech, urging tech workers to consider the balance between self-interest and the public good, and to refer to ACM's Code of Ethics, emphasizing the support of the public good. The article discusses cases like Uber, illustrating how employees, even unknowingly, can participate in unethical practices. Ultimately, Vardi concludes that the tech industry needs a serious self-reflection to address its ethical dilemmas.

Pre-Modern Peasant Marriage Patterns: A Cross-Cultural Perspective

This article explores marriage patterns among pre-modern peasant populations, highlighting that while high mortality rates led to diverse household structures, marriage was a universal and strictly enforced social norm. Three marriage patterns are analyzed: an early pattern (average female age at first marriage around 16, e.g., ancient Greece), an intermediate pattern (average female age at first marriage around 20, e.g., Rome), and a late pattern (average female age at first marriage around 25, e.g., early modern Western Europe). These patterns are closely linked to women's social status, fertility control strategies, and household structures. The late pattern is particularly unique, associated with high percentages of never-married individuals and newly married couples forming independent households. The article emphasizes the significant differences between elite and commoner marriage patterns and notes that marriage in these societies wasn't an expression of individual affection but a necessary component of fulfilling social roles.
