Ethical Approaches

The PDF introduces various ethical approaches to understanding AI, with a strong emphasis on virtue ethics. This ethical framework focuses on the character and virtues of individuals rather than solely on the consequences of actions. By promoting human flourishing, virtue ethics encourages the development of AI systems that enhance well-being and societal good. This approach is crucial in guiding the design and implementation of AI technologies that align with human values.

Purposes of AI

AI can serve multiple purposes, which are categorized into three main areas: efficiency, social control, and human flourishing. AI for efficiency focuses on optimizing processes and maximizing profits, while AI for social control involves using technology to monitor and regulate behavior. In contrast, AI for human flourishing aims to enhance the quality of life and promote well-being. Understanding these purposes is essential for ethical evaluations of AI applications and their societal implications.

Machine Learning and Narrow AI

Machine learning is a significant aspect of AI, characterized as a form of narrow AI. It excels in specific tasks, such as image recognition and natural language processing, but lacks the ability to transfer knowledge across different domains. For instance, a machine learning model trained to identify cats and dogs cannot automatically recognize human emotions. This limitation highlights the need for careful consideration of the applications and implications of machine learning technologies.

Opacity and Unpredictability

One of the critical challenges in machine learning is its opacity. The algorithms and neural networks used in these systems are often so complex that even experts struggle to understand their internal workings. This lack of transparency leads to unpredictability in the outputs generated by these systems, making it difficult to anticipate their behavior based on input data. Addressing these issues is vital for ensuring accountability and trust in AI technologies.

Big Data Requirements

Machine learning systems typically require vast amounts of data to function effectively. This reliance on big data presents ethical concerns regarding privacy, consent, and data ownership. The need for significant computational resources to create and train models further complicates the landscape of AI development. As such, it is essential to consider the ethical implications of data collection and usage in the context of machine learning.
