AI Won't Make Your Senior Engineers 10x Faster

The AI Productivity Gap

Despite AI's promise, senior developers save only about 15% of their time, while juniors gain 25%. The reason: coding is a small part of the job. Most time goes to design, debugging, reviews, and meetings—areas AI hasn't transformed. Ironically, leaders who think AI replaces juniors are wrong; juniors benefit most, especially when using AI as a learning tool.
