The AI Daily Brief: Artificial Intelligence News and AnalysisWhy AI Skeptics Are NutsToday on the AI Daily Brief, NLW dives into a provocative essay that's shaking up the AI conversation: "My AI Skeptic Friends Are All Nuts," by Thomas Ptacek. Focusing on AI-assisted coding, Thomas dismantles popular skeptic arguments, highlights why serious coders using AI agents are already far ahead, and explains why dismissing AI is no longer justifiable. Beyond coding, this episode explores how rapidly we're shifting from AI as mere assistants to true collaborative agents, transforming the way we work, compete, and innovate—whether you're ready or not.Source: https://fly.io/blog/youre-all-nuts/...

Dans discusses the limitations and progress of generative AI in complex tasks like programming and academic research, referencing critiques from developers like Thomas Ptacek and his own experiences using AI for structuring academic papers versus the actual research.
