The personal computer brought computing power out of governments, universities, and corporations and into homes and offices. That shift changed who could create, calculate, design, write, and program. A tool once reserved for specialists became a general-purpose machine for ordinary people.

The PC also changed culture. It made digital work mainstream, helped create the software industry, and laid the groundwork for the internet economy. The modern knowledge worker is, in many ways, a child of the personal computer revolution.
