Every era's transition is essentially an iteration of productivity tools. The steam engine ushered in the Industrial Age, electricity illuminated modern cities, and chips drove the information revolution. Today, the AI wave is sweeping in—whoever can master this power first will hold the key to the era.

Imagine Pittsburgh in the mid-19th century. At that time, the United States was still an agricultural country, with six out of ten people farming. A young telegraph operator named Carnegie saw the potential in the steel industry. In just two generations, he transformed the entire world—railroads replaced carriages, electric lights dispelled candles, and steel became the backbone of construction.

The nature of work also changed dramatically. People moved from fields into factories, and then from factories into offices. Now? Two billion knowledge workers worldwide are sitting in offices. AI has knocked on the door, but most people haven't yet responded.

Interestingly, new technologies often appear "dressed in old clothes." Early telephones mimicked the style of telegraphs, and the first films involved setting up a camera to film stage plays. This means we always interpret the future through the lens of the past. What will the future of knowledge work look like? When AI becomes part of organizations—thinking and executing tirelessly—what will happen to the office? This is a question worth everyone pondering.
