    Before Douglas Engelbart, computers were as big as rooms and used mostly for handling numbers. But in the late ‘60s’at the Stanford Research Institute, Engelbart invented almost everything your personal computer has today: a mouse, hypertext, screen sharing and more. In 1968 he made real-time edits to documents nearly 40 years before Google Docs hit screens; video chatted with friends long before Skype’s 2003 arrival; and resized windows years before Microsoft entered the field in 1975. Engelbart was adding graphics (图形), hyperlinking and sharing screens — all before the birth of the World Wide Web. “The digital revolution is far more significant than the invention of writing or even of printing,” said Engelbart, and as it turns out, he held all the right cards.

If he’d been British，Engelbart would have been knighted (授爵), but the Portland, Oregon, native instead lived out the rest of his years as an unsung hero, trying to fry even bigger fish in Silicon Valley. His blueprint of the Internet was radically different from today’s profit- driven, streamlined version. Engelbart imagined an information system built on the backbones of cooperation and education, all meant to enhance the collective human mind. He wanted a computerized network of real-time, human-wide cooperation, with the open-source spirit of Wikipedia and the purposefulness of Change.org.

By the late 70s and early ‘80s’ Engelbart and his ideas were cast aside in favor of Apple Macintosh and Microsoft Windows, along with their profit-generating vision for personal computing, and a user-friendly approach to the Internet. Engelbart’s team of researchers abandoned him, and he had a lesser position at a company called Tymshare while still battling with his pie-in-the-sky visions of a better world. Even worse, when Engelbart’s mouse invention gained widespread use years later, he never gained the profits — it had been licensed to Apple for around $40,000, Engelbart revealed.

And if Engelbart had won? “Hard to say,” says Jefferson Bailey of the Internet Archive in San Francisco. The Web was bound to grow in ways its founders never intended, he says. He notes his belief that the same spirit of knowledge-sharing and cooperation Engelbart tirelessly pushed for will one day become part of our fast-evolving Internet, even if a commercial layer clouds the original vision. But even so，fame is difficult to achieve; it often ridicules great thinkers like Galileo or Tesla, only to meet them decades after death. Granted, Engelbart was eventually allowed into the National Inventors Hall of Fame, in 1988, and into the Pioneers Circle in the Internet Hall of Fame after his death, but the heart of his dream has yet to be realized.
