The AI Development Paradox: Why AI Gets More Expensive as Systems Grow — Even as Models Improve

TL;DR AI is a superpower at the early stages of product development: it accelerates prototyping, fills in boilerplate, and helps teams move fast. But as systems grow, a paradox emerges: the more complex the product becomes, the worse AI performs — and the more expensive it becomes to use safely. Even with larger models, bigger context windows, and multi agent pipelines, AI still misinterprets instructions, hallucinates, and makes bold but wrong assumptions. The result: the true cost of AI rises
