I think Xerox Star is the system that made a really significant turning point in computer history. Until then, computers were difficult machines that needed to be used only by memorizing and typing commands. However, Star began transforming computers into tools that anyone could use by introducing the Graphic User Interface, such as mouse, icons, and desktop screens for the first time. There was no longer need to write documents in complex code, and intuitive manipulations such as drag and copy were now possible. It was not just a technological advancement, it was an event that changed the essential use experience (UX) of a computer itself.
Personally, I feel that the moment when Xerox Star appeared is similar to the moment when primitive people first discovered fire. Technology, previously available to only a few experts, began to open up to the public through Star, and humans were only able to communicate with computers. Star was not very commercially successful, but it was followed by Apple Macintosh and Microsoft Windows, and all the computer interfaces we use today were affected. I think Xerox Star’s transformation was more than just software design and the beginning of an era where technology is tailored to humans. So I would like to say that Xerox Star was too valuable a legacy to be buried in history and was a real innovation that exploded in computer accessibility.
