Not to diminish the many contributions from others, but it's entirely possible to imagine that, without Steve Jobs, "personal computers" might never have entered the mainstream. HP dismissed the idea outright, and IBM took a relative eternity to participate after seeing the promise in the market that Jobs helped create. Without personal computers, the Internet as we know it might be unrecognizably restricted to soldiers and scholars, and who knows what inspiration Tim Berners-Lee might have lacked had he not been working on a NeXT machine at CERN.
