Critical Analysis of Abstraction in Software Development: When Hiding Details Harms System Reliability

Summary

The article presents a critical examination of abstraction in software development, challenging the conventional wisdom that abstraction is essential for modularization and system reliability. The author argues that while abstraction is widely accepted as necessary for managing complexity, it actually prevents guaranteeing reliability and correctness at the whole system level. The piece explores how abstractions hide implementation details that can become critical as systems evolve, potentially leading to failures when hidden assumptions break down. The author suggests that the very property of abstraction that makes it useful—hiding details—also makes it dangerous for long-term system reliability.
