From encyclopedias to AI: How knowledge is changing the way we work

For most of human history, knowledge wasn’t something you could access instantly. It was scarce, slow to move, and often held by institutions built to store and interpret it. Universities, libraries, and professional guilds played that role for generations. If you wanted to learn something, you turned to a trusted source—such as a teacher, a textbook, or an encyclopedia—and worked through it over time. The times today are very different. The shift from encyclopedias to artificial intelligence isn’t just a technology upgrade, it’s a fundamental change in how we interact with knowledge. It’s reshaping how we work, how organizations operate, and how opportunity gets distributed. That’s why AI is becoming such a defining force in this next chapter of work and life. The evolution of knowledge tools If you look back, there’s a clear progression in how we access knowledge. In the encyclopedia era, information was static and curated. It was reliable, but finding and interpreting it took time. The search engine era changed speed and access. You could type a question and get thousands of results instantly but the responsibility still sat with the individual to evaluate, synthesize, and decide the relevance. Then came the platform and data era. Software organized information into dashboards and workflows, giving people real-time visibility. Decisions became more informed, but humans still had to interpret the data and turn it into action. Now we’re entering the AI era. These systems not only retrieve information but also help make sense of it, including analyzing, summarizing and, increasingly, doing. Instead of spending hours searching, you can ask a question and get a structured answer, a recommendation, or even a draft of the work. Across these stages, the role of the individual has evolved from being a researcher to a navigator to a data-driven decision-maker, and now to a director of intelligent systems. It’s been a subtle shift, but an extraordinary one in terms of how w
