By 2028, dev teams not using AI tools will lose competitiveness.
The Data
Y Combinator Winter 2025: A quarter of startups have 95% AI-generated code.
BettaFish project: 20-year-old student built a sentiment analysis system with AI. 24.7k GitHub stars.
Traditional approach? Impossible.
What Is Vibe Coding
Term coined by Andrej Karpathy. Collins Dictionary Word of the Year 2025.
Core idea: Describe problems in natural language, AI generates software.
Not "AI helps you write code."
It's "you describe intent, AI implements."
The Efficiency Formula
Requirements to prototype: AI generates 70%, 2 weeks → 2 days
Feature implementation: AI generates 50%, 4 weeks → 2 weeks
Testing & optimization: AI generates 30%, 2 weeks → 1 week
Total cycle: 8 weeks → 5 weeks. 37.5% improvement.
The Key
Don't let AI generate randomly.
Define clear modular architecture first, then let AI generate each module.
Repetitive work goes to AI. Core algorithms stay with you.
Human-AI collaboration, not replacement.
The Essence
The definition of technical ability has changed.
Not "how many lines of code can you write."
It's "how complex a problem can you solve with AI."
Age, experience, credentials—no longer barriers.
The real barrier is mindset—whether you're willing to embrace the new paradigm.
Is your team ready?
