Douglas Engelbart’s 1968 demo, often called the “Mother of All Demos,” didn’t just change computing it completely reimagined what computers could be. At a time when computers were seen as giant number crunching machines, Engelbart and his team at the Stanford Research Institute (SRI) showed the world a future where computers could be intuitive, visual, and even collaborative. It’s hard to overstate how groundbreaking this was. Imagine sitting in that audience, watching someone use a computer mouse for the first time, clicking and navigating on a screen like it was the most natural thing in the world. Today, we take that for granted, but back then, it must have felt like magic. The demo wasn’t just about the mouse, though. Engelbart introduced graphical user interfaces (GUIs), complete with windows and hypertext links ideas that would later become the foundation of modern operating systems like macOS and Windows. And then there was real-time collaboration. Yes, in 1968, Engelbart’s team demonstrated multiple people editing a document simultaneously, something we now do every day with tools like Google Docs. It’s almost funny to think that we’re still catching up to some of his ideas today. What’s even more fascinating is how Engelbart’s vision rippled through the tech world. His work directly inspired Xerox PARC, which in turn influenced Apple and Microsoft. Without Engelbart, we might still be typing commands into a black-and-green terminal instead of swiping and tapping on sleek, colorful screens. He didn’t just invent tools; he redefined how we think about computers not as cold, calculating machines, but as extensions of our creativity and communication. Looking back, it’s clear that Engelbart’s demo wasn’t just a presentation; it was a revolution. It’s a reminder that the most transformative ideas don’t just solve problems they change the way we see the world. And honestly, isn’t that what great technology is all about?
