Knowledge

The stock of accessible human knowledge has grown, over the last thirty years, more than in any comparable period in human history.

Before 1995, if you wanted to learn something, you needed to be near a library that had a book about it, or near a person who knew it, or enrolled in a school that taught it. All three of those gates excluded enormous numbers of people. A smart child in rural Indonesia, in 1985, had essentially no path from “curiosity about how the human immune system works” to “reliable information about how the human immune system works.” A smart child in rural Indonesia in 2026 has Wikipedia in Indonesian, plus YouTube explainer videos, plus, increasingly, AI tutors that can explain the material at any level of depth the child wants.

The degree to which this has flattened access to information is hard to state without sounding like a brochure. So let me state it bluntly: never before in human history has so much of what humanity knows been accessible to so many humans, regardless of where they live, how much money their family has, or what schools they can attend. The gap between a rich-country education and a poor-country education is still real, but it is smaller — for the motivated student — than it has been at any previous point.

AI tutoring is still early, and the evidence on whether it actually helps kids learn is mixed. But it is getting better quickly, and the underlying technology — good AI, available over the internet, accessible from a cheap phone — is already in the hands of several billion people. The outcomes five or ten years from now are likely to be substantially better than they are today, if the technology develops even approximately as expected.

None of this solves unequal education by itself. The child who wakes up without breakfast, in a home where no one expects her to go to college, still faces almost everything that’s hard about being that child. But the information gate — the specific barrier of “I cannot find out what I want to know” — is lower than it has been in any previous generation, and the primary reason is the chip-and-data-center stack.
