Computers—the machines we think with

While you read these words, invisible machines are already crunching millions of calculations, translating text, and tallying bank checks in a heartbeat. The 1960s have seen a rapid surge in computer use—from government censuses and postal sorting to airline ticketing and missile guidance—turning what were once massive, room‑filling devices into tools that fit in the palm of a hand. Even everyday commerce, such as library loan accounting and retail transactions, now relies on electronic processing, revealing how deeply the technology has slipped into the fabric of daily life.

Beyond business, computers are reshaping science and industry, solving problems that would otherwise take humans forever. They steer rockets, forecast weather, and run entire factories, while early robotic arms learn to perform repetitive tasks with precision. As designers hand over the blueprint of new machines to computer programs, the boundaries of what can be invented expand, hinting at a future where thinking machines not only augment our work but begin to design the next generation of themselves.
