- ‘I”d Rather Read the Prompt’: In his article “I’d Rather Read the Prompt,” Clayton Ramsey critiques the reliance on large language models, such as ChatGPT, for writing and academic work. He argues that these models produce verbose, uninspired content lacking originality or meaningful human insight. Ramsey emphasizes the importance of communicating original thoughts, suggesting that using AI-generated text is worse than plagiarism, as it conveys no authentic human perspective. He warns that this reliance, particularly in educational and professional settings, undermines genuine learning and understanding. Ramsey argues that both creative writing and programming should involve personal insight and comprehension rather than being left to automated processes that result in hollow, error-prone outputs. Ultimately, he asserts that creative work should convey genuine personal experiences, and if it’s not worth the time to write authentically, it’s not worth reading.
Data Science
- ‘Spatial Machine Learning With Caret’: The text discusses the integration of the caret machine learning workflow with spatial data processing packages like blockCV and CAST, emphasizing handling spatial autocorrelation and extrapolation. It covers spatial cross-validation methods using
blockCV::cv_spatial()andCAST::knndm(), which help prevent overly optimistic errors by managing training and testing data distribution. Feature selection and hyperparameter tuning enhance model generalizability, whileCAST::aoa()is used to identify areas where model predictions are unreliable. - ‘Measuring What Matters: Objective Metrics for Image Generation Assessment’: Evaluating image quality is complex, requiring clear, objective metrics to assess the creativity, realism, and style of AI-generated images. Human feedback is often biased and inconsistent, so metrics like Fréchet Inception Distance (FID) and Clip Maximum-Mean-Discrepancy (CMMD) are used to measure how close generated images are to real ones. Pruna’s open-source evaluation framework enables both single and pairwise assessments using various metrics. Users can customize these metrics for tailored evaluations, essential as AI images grow in use.
Economics
- ‘Goodhart”s Law Isn”t as Useful as You Might Think’: Cedric Chin argues that Goodhart’s Law, which warns against metrics manipulation, is less practical than Donald Wheeler’s approach from “Understanding Variation.” Wheeler’s perspective suggests three responses to target pressure: improving, distorting the system, or data. The solution involves making distortion difficult and allowing system improvements, requiring a focus on process inputs rather than outcome fixation. Chin highlights Amazon’s Weekly Business Review as an example of effective input metric management employing Statistical Process Control principles, enabling leadership to build a causal business model.
- ‘Pánico Moral Con La Inteligencia Artificial Y Que La Mayoría De Los Empleos Sean Cosas Del Pasado’: Antonio Ortiz discusses the moral panic surrounding AI and its impact on employment. The article highlights concerns about rising unemployment among recent US graduates, as AI increasingly replaces junior roles traditionally held by new graduates. Leading tech companies are reducing hiring or even laying off workers, such as Microsoft with 6000 employees. While some argue that AI-induced job losses are transient, others worry about rapid, irreversible changes. The EU’s regulatory response aims to balance competitiveness with precaution, yet critics say it’s driven by fear rather than current realities. The race for AI dominance is primarily between China and the US, pushing Europe to reconsider its regulatory stance.
- ‘The Fugu Guide to Jobs in a World of AI’: In “The Fugu Guide to Jobs in a World of AI,” Sangeet Paul Choudary discusses the shifting dynamics of labor as AI transforms scarcity in knowledge work. With AI handling routine tasks, the new constraints lie in areas such as trust, context, and judgment, where human skills remain crucial. Roles must adapt by focusing on interpretation and decision-making. The most valuable positions hold high contextual and economic value, created by understanding and resolving challenges AI cannot address. This strategic thinking rather than mere reskilling is key to thriving alongside AI.
Philosophy
- ‘Extending Minds With Generative AI’: Andy Clark’s article discusses the implications of generative AI and technological advancements on human cognition. He highlights historical fears of technology diminishing cognitive abilities, akin to past concerns about reading and writing. Today, worries persist that technology might replace rather than extend our minds, leading to reduced reliance on biological memory and creativity. Clark suggests that humans have always evolved as “extended minds,” synergistically incorporating non-biological resources. While new tools like AI pose challenges, they also offer opportunities to augment human intelligence. The key is developing skills to discern when and how to rely on these tools, ensuring they complement rather than overshadow innate cognitive capabilities. Education must adapt to teach these “metacognitive” skills, fostering informed interactions with AI to ensure technology serves human needs.
- ‘Quoting Neal Stephenson’: Simon Willison’s Weblog discusses the impact of technology on society, quoting Marshall McLuhan’s idea that every technological augmentation is also an amputation. The piece highlights the significant influence of AI, suggesting it brings about changes far beyond McLuhan’s predictions. Concerns are raised about AI systems, such as ChatGPT, as educators observe that students increasingly rely on them, potentially hindering learning. This phenomenon is highlighted as a major current worry regarding AI’s role in education.
Software Engineering
- ‘8 Powerful Steps for an AI-Assisted Development Workflow’: The article by Tsvetan Tsvetanov outlines an efficient AI-assisted development workflow in 8 steps, emphasizing the importance of human leadership and vertical slicing. The workflow involves breaking down requirements into small, deployable pieces known as vertical slices, focusing on design, and providing exhaustive examples for the AI to generate solutions. Human oversight in validating tests and implementation ensures code reliability.

- ‘After Months of Coding With LLMs, I”m Going Back to Using My Brain’: After months of coding with large language models (LLMs), experienced developer Alberto Fortin decided to return to a more traditional approach, involving his own critical thinking. While using AI tools like Claude and Cursor to rewrite a system in Go and ClickHouse, Fortin noticed inconsistencies and redundancies in the generated code. This led him to reevaluate his methods, ultimately opting for a more hands-on approach—using pen and paper and coding initial drafts himself, treating AI as an assistant rather than the main creator.
- ‘Squelching Bad Vibe Coding’: Jeff Langr’s article discusses the challenges and strategies of AI-assisted development with an emphasis on improving code quality and test verification. Initially attempting test-driven development (TDD) with a large language model (LLM), Langr found it inadequate and shifted towards a method he terms AADV (AI-Assisted Development with Verification). This approach involves the CAX (Create, Assess, Execute) cycle, where both code and tests are generated, assessed, and executed until passing. The process emphasizes design guidelines to enhance code quality and compliance. Langr warns of the proliferation of low-quality AI-generated code but argues that combining design principles and testing can improve outcomes.
Management
- ‘The Role of the Chief AI Officer (CAIO): A Guide to Leading the Transformation Toward Artificial Intelligence’: The role of a Chief AI Officer (CAIO) has become critical as AI transforms business operations. The CAIO not only leads AI adoption but also drives the cultural shift necessary for integration. Their responsibilities include defining AI initiatives, driving cultural change and skill-building, and bridging the gap between technology and business needs. They must also address risks related to fairness, accountability, transparency, and ethics, ensuring AI aligns with company values. Despite advances in AI, many firms are early in their adoption. Therefore, prioritizing strategic AI adoption and fostering a culture open to change is essential. The future of the CAIO role is integral in shaping agile and responsible organizations.
