The Adjacent Possible

Stuart Kauffman coined the term "the adjacent possible" to describe the set of all things that are one step away from what currently exists. In biology, it's the set of molecules that could form from the molecules already present. In technology, it's the set of inventions that could be built from the components already available. In creative work, it's the set of ideas that are reachable from where you currently stand.

It's a concept I think about constantly, because it explains something that's otherwise hard to articulate: why the best innovations feel simultaneously surprising and inevitable.

We love stories about revolutionary breakthroughs. The lone genius who sees what no one else can see. The startup that disrupts an entire industry with a radical new idea. The moment of inspiration that changes everything.

These stories are almost always wrong, or at least heavily edited. When you look at the history of any significant innovation, what you find is not a leap but a series of steps. Each step was possible because of what came before. Each step opened up new possibilities that weren't accessible before.

The iPhone didn't come from nowhere. It came from decades of touchscreen research, mobile computing development, miniaturized sensors, and cellular infrastructure. It was, in 2007, adjacent to what already existed. That doesn't make it less impressive — it makes it more impressive, because it means someone looked at the landscape of what was possible and saw a combination that no one else had assembled.

If you're trying to build something new — a product, a platform, a company, a creative work — the adjacent possible is the most useful constraint you can apply to your thinking.

It means asking: what's one step away from what I already have? What could I build with the components that are already available to me? What combination of existing things would create something genuinely new?

This isn't settling for incrementalism. The adjacent possible can be enormous. It's not about making small improvements to existing things — it's about seeing connections between existing things that create something qualitatively different. The web browser was adjacent to hypertext and networking. Wikipedia was adjacent to the web browser and the tradition of encyclopedias. Neither was incremental. Both were adjacent.

What I love about this framework is that it's simultaneously ambitious and disciplined. It encourages you to think big — the adjacent possible is vast, full of unexplored combinations — while keeping you grounded in reality. You're not fantasizing about what might be possible in ten years with unlimited resources. You're looking at what's possible right now, with what you have.

In practice, this means paying deep attention to what already exists. To the tools, technologies, behaviors, and cultural shifts that are already in motion. The best innovations don't fight the current — they ride it in a direction no one expected.

It also means being suspicious of ideas that require too many things to change simultaneously. If your product needs users to adopt new hardware, learn new mental models, and change established habits all at the same time, you're probably not in the adjacent possible. You're in the distant possible, which is a fancy way of saying you're probably too early.

I try to apply this thinking to my own work. When starting a new project, I ask: what do I already know how to build? What tools do I already have? What skills, relationships, and insights am I already sitting on? And then: what could I combine from that inventory to create something new?

The answers are usually more interesting than whatever I'd dream up from scratch. Because the adjacent possible isn't limited by my imagination — it's expanded by it. The more I know about what exists, the more combinations I can see. The more combinations I can see, the larger my adjacent possible becomes.

Innovation, it turns out, isn't about seeing further than everyone else. It's about seeing more clearly what's right in front of you.
