The Productivity Reality

AI doesn’t write your code. It removes friction.

Where AI helps most:

• Boilerplate (saves 50%+ time)
• Syntax you forget (regex, shell commands)
• Understanding unfamiliar codebases
• First drafts of implementations
• Explaining errors

Where AI still struggles:

• Novel architecture decisions
• Complex business logic
• Performance optimization
• Security-critical code
• Understanding your specific context

The best developers use AI for speed, not as a replacement for thinking.
