Why Codex Is the Beginning of New Engineering

The way we write code just changed forever. OpenAI’s latest updates to Codex aren’t just a small step forward—they’re a whole new chapter in engineering. In this video, I walk you through what’s really happening with Codex across the cloud, desktop (CLI), GitHub integrations, and even VS Code extensions. You’ll see me experiment live: from adding playful sparkles to a homepage logo, to swapping out fonts across an app, to spinning up pull requests and letting Codex review them. Along the way, I share why this shift is about more than faster coding—it’s about scaling yourself from one developer into ten. By the end, you’ll see the full lifecycle: firing off multiple requests, reviewing results, merging PRs, and understanding how this ties into Git workflows. This is the first real glimpse of what “new engineering” looks like—and it’s already here, for just $20 a month. Come along as I explore what might be the most important shift in software development we’ve seen in years. #Codex #OpenAI #AIProgramming #SoftwareEngineering #GitHub #VSCode #DeveloperTools #FutureOfCoding #AIinEngineering 00:00 - Intro 00:29 - Codex Parts Described 02:49 - The Sample Application 03:41 - Learning Codex Cloud 06:45 - CodexCLI our old friend 07:53 - The Codex IDE Extension 10:07 - Creating a PR 11:33 - Git Process Described 14:44 - Can still request after creating a PR 15:19 - Investigating our PR 16:33 - Applying cloud changes dierectly 18:02 - What happens in Cloud Codex? 19:37 - Pulliing our branch 20:27 - CODEX COOKED! 21:15 - PR Reviewer 22:28 - Final PR Review 23:22 - Conclusion
