Parallel AI agents are a game changer

Summary

I’ve been in this industry long enough to watch technologies come and go. I’ve seen the excitement around new frameworks, the promises of revolutionary tools, and the breathless predictions about what would “change everything.” Most of the time, these technologies turned out to be incremental improvements wrapped in marketing hyperbole. But parallel agents? This is different. This is the first time I can say, without any exaggeration, that I’m witnessing technology that will fundamentally transform how we develop software. How We Got Here To understand where we are today, we need to look at the full history of AI-assisted coding. It started with GitHub Copilot, which introduced the concept of AI pair programming. Copilot could autocomplete code as you typed, suggesting functions, completing implementations, and helping with repetitive tasks. Then came the AI-powered editors like Windsurf and Cursor. These took the concept further by integrating AI deeply into the development environment. Instead of just autocomplete, you could have conversations with AI about your code, ask for refactoring suggestions, and get help with debugging. The AI understood your entire codebase and could provide contextual assistance. This year, we’ve been working with what’s called “vibe coding” — AI tools where you describe what you want in natural language, and the AI generates complete functions, classes, or implementations from scratch. You tell it “create a sign up form with google, github, and microsoft login options” and it produces working code that captures the vibe of what you asked for. The term “vibe coding” was coined by Andrej Karpathy in this tweet, which perfectly captured what this new way of programming felt like. There’s a new kind of coding I call “vibe coding”, where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It’s possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good. Also I just talk to Composer ...
