The "Tesla Moment" for Software Development

Replit just hit a massive milestone with Agent 3 – imagine having a senior developer who can debug your code for hours without getting tired or stuck. @amasad calls it "the Full Self-Driving moment of software".

What's Different About Agent 3?

1. True Autonomy: Unlike GitHub Copilot or ChatGPT, Agent 3 keeps working for 200+ minutes without human input
2. Full Testing Loop: Identifies bugs, writes tests, fixes code, validates changes
3. Legacy Code Friendly: Handles complex, existing codebases without getting lost

Quick Start for Founders

1. Open Replit and create a new project
2. Enable Agent 3 in settings
3. Use the "Debug" command
4. Set autonomy level (start with "Supervised")
5. Watch as it methodically fixes your codebase

Pro Tip: Start Small

Begin with a single feature or bug. Agent 3 excels at focused tasks before tackling larger refactors.
