Why Programmers Should Use AI
AI is a force multiplier. It helps automate repetitive work, provides learning shortcuts, and speeds up experimentation. Developers who adopt AI tools will iterate faster and deliver more value.
Quick Tips for Effective Use
- Provide a clear context and expected output when prompting an AI tool.
- Ask for explanations and edge cases instead of only code.
- Verify and test generated code — AI suggests, you validate.
- Use AI for scaffolding; keep core logic and design decisions manual.
