The AI Costly Illusion: How Cloud Quotas & Bad Architectural Advice From Codex Wasted My Data Project

When AI Assistants Meet Reality: A Cloud vs Bare Metal Showdown for Big Data Can AI programming assistants truly handle production-grade data analytics? My experiment analyzing Common Crawl data reveals they excel at code generation but fail at system-level judgment, making human oversight critical for architecture decisions.
