I've been coding for 12 years. GitHub Copilot added roughly 30% to my output speed — and I wasn't slow to begin with. The context-aware suggestions in VS Code are spookily good. It anticipates entire functions from a comment. The GPT-4 powered chat in Copilot X is even better for complex refactoring.

Pros

Massively speeds up boilerplate
Great context awareness
Copilot Chat is excellent

Cons

–Occasionally suggests outdated patterns
–Needs careful review for security code
