Key Takeaways

  • AI tools like OpenAI's Codex have made the actual _building_ of software inexpensive, shifting the biggest cost in product development away from implementation.
  • The new bottleneck is "taste" and "curation" – the skill to sift through a multitude of AI-generated prototypes, identify what's good, and refine it into a superior product.
  • Traditional product planning, which focused on extensive documentation (like PRDs) to de-risk costly implementation upfront, is now "backwards." The value lies in quick iteration and selection.
  • The most valuable people today are “high agency, high taste” builders who can quickly take an idea from a rough concept to a polished, refined product, overseeing its development with a keen eye for quality.

The AI Inversion: Your New Product Cost is Taste

For decades, building software was expensive. Lines of code meant time, developers, and significant resources. Andrew Ambrosino, product and engineering lead for OpenAI's Codex app, says that's over. Thanks to AI, he explains, “The implementation is actually not the expensive part anymore. It's dare I say taste.” This isn't just a slight shift; it's a fundamental inversion of how products are made and what skills matter most.

Think about it: if AI can spin up a dozen prototypes in the time it used to take to spec out one, your problem isn't getting code written. Your problem is picking the _right_ code. Ambrosino emphasizes this new reality: “It's the curation process. It's like of those 90 attempts like what's good about these? What should we fold into other aspects of this?” The effort moves from careful, slow construction to rapid generation and discerning selection. Traditional product development methods, with their heavy emphasis on detailed PRDs and upfront de-risking, are simply "backwards" in this new world. They were designed for a scarcity of implementation, not an abundance.

The Rise of the “High Taste, High Agency” Builder

In this flipped landscape, the person who can identify potential and refine it becomes king. Lenny Rachitsky put it directly: “The most valuable person right now… is someone that could take an idea from idea to done with the taste to know this is great. Just like shephering throughout this obsession with making it awesome like this kind of high agency, high taste person.” This isn't just about aesthetics, though that's part of it. Ambrosino adds, “there is an aesthetic part to it. Um but there's also a a systems thinking part of it. Like how does this fit in the system? There's a where are we going and how like what what theme is this part of?” It's about knowing what truly works, how it integrates, and how it aligns with the larger vision of the product.

This kind of taste isn't something you get from reading a textbook. It comes from iterating, from seeing many bad attempts, and from developing a sharp intuition for what makes a product click. It means moving fast, trying many things, and having the discernment to cut ruthlessly or combine cleverly. The ability to shepherd an idea through countless rapid iterations, continually elevating it, is the superpower of the AI era.

What to Do With This

This week, shift your team's focus from detailed upfront documentation to rapid, AI-assisted prototyping. Challenge your product leads to generate five distinct prototypes for your next feature, then spend time ruthlessly curating and refining the best elements rather than perfecting a single spec. Prioritize hiring and developing individuals who demonstrate strong "taste" and "systems thinking" over those who excel solely at traditional project management or deep coding.
