Agentic AI: When AI Systems Act Independently

# What Devin can do autonomously:
- Read requirements and create project plans
- Write complete applications from scratch
- Debug existing codebases independently
- Deploy applications to production
- Collaborate with human developers via Slack

# Example interaction:
Human: "Build a website that tracks cryptocurrency prices"
Devin: "I'll create a React app with real-time crypto data.
       Let me break this down:
       1. Set up React project with TypeScript
       2. Integrate CoinGecko API for price data
       3. Create responsive dashboard with charts
       4. Add price alerts functionality
       5. Deploy to Vercel
       
       Starting now... [begins coding]"
