At the beginning of Zero to One, the author raises a famous interview question and promises to give his own answer later in the chapter. However, after finishing Chapter 1, I still couldn’t find a clear answer. It was only after asking an AI that I realized his implied answer: technological innovation matters more than globalization or scale-up.

In a way, this feels a little sneaky. The author presents what is essentially a value judgment as if it were an objective truth. Because the claim is broad and difficult to falsify, it also becomes difficult to refute.

The book itself is written from the perspective of an early-stage investor. Much of the argument can be understood as advice on how venture capitalists evaluate potential startups—looking for companies that can create something genuinely new and dominate a niche market.

However, looking back more than ten years later, the author’s own investment focus has shifted toward areas such as defense technology, artificial intelligence, and national security. In that sense, the certainty of geopolitics and state power sometimes appears more predictable than the uncertain path of technological innovation.

This shift raises an interesting question: if technological breakthroughs are so central to building the future, why do many influential investors eventually turn toward sectors tied closely to governments and geopolitical competition?

Perhaps the deeper lesson of the book is not simply about innovation itself, but about identifying where the next structural advantage will emerge—whether in technology, markets, or geopolitical power.
