How To Build The Future: Paul Graham & Amjad Masad
Categories: VC, Startup, Design
Summary
Replit was already generating 50-60% of code through autocomplete before launching full AI coding—they discovered users were manually copy-pasting between ChatGPT and their IDE, revealing the real gap wasn't AI capability but automating the loop-to-completion workflow. This incremental observation turned into what Andrew Karpathy called an AGI moment.
Key Takeaways
- Watch your users struggle with manual workarounds. Replit invited users to the office and observed them copying errors between ChatGPT and their IDE—this manual feedback loop became the product insight that drove vibe coding.
- AI agent capability follows predictable progression: the harness circuit in 2024 was 10x more complex than today because earlier models were less capable. As models improve, the engineering overhead to reach completion decreases—but commoditization accelerates.
- The real moat isn't the AI model—it's owned infrastructure. Replit's ability to provision databases, Redis, and hosting through tool calls was a major differentiator. Competitors without backend infrastructure face structural disadvantages.
- Accept permanent commoditization in AI. Every feature you build gets copied as models improve. The strategy isn't defensibility through current AI capability—it's relentless execution on the next hard problem.
- Incremental iteration beats grand departure. Replit didn't suddenly pivot to AI coding; they moved from 50-60% AI-generated code to 100%. User behavior (already using AI heavily) validated the direction before the big bet.

I think with AI, everyone will have to go through this period of denial and then depression and then eventually acceptance. Replet's like this iceberg where there's this visible bit above the water that's like look you just tell it in English what to do and it writes your code and then underneath there's all this stuff for deployment and sand. >> I don't think we describe ourselves as v coding. Now we think replet is the platform for the transformation for to self-driving companies >> more than other companies though I think you guys are have been living in the future if you had to say like what's the real DNA of replet >> it is living in the future for sure. So you guys basically invented vibe coding right? >> And when you did it like in 2024 this was, which it sounds it's like only two y…
