Over-engineering occurs when software architecture prioritizes complexity over simplicity, often driven by trends, resume-driven development, and misaligned incentives. This approach can lead to slower delivery, increased fragility, and ultimately fails to address real user needs. Emphasizing simplicity and context-aware design can foster more effective and resilient systems.

The article discusses the rise of single-node architectures as a rebellion against traditional multi-node systems in data engineering. It highlights the advantages of simplicity, cost-effectiveness, and ease of management that single-node setups provide, particularly for smaller projects and startups. The piece also explores the implications for scalability and performance in various use cases.
