The 10x Illusion: If AI Codes 10x Faster, How Much Faster Do Projects Actually Ship?

AI coding tools are getting shockingly good. So it’s natural to ask: if the coding part gets 10x faster, shouldn’t the whole project get 10x faster too?

The answer is surprisingly counterintuitive — and backed by a growing body of data.

The Speed Is Real. The Extrapolation Is Not

AI coding tools deliver genuine speed on implementation tasks. GitHub Copilot studies show developers completing isolated coding tasks 55% faster. AI agents can generate entire modules in minutes. The speed is not the illusion.
