I can't think of another person this past century who would match Steve Jobs's vision. He was one of those rare persons with an ability to identify opportunities. But you also have to remember that Steve was no engineer. He was the visionary and surrounded himself with those who would buy into his vision and deliver. It all started with Steve and Woz, then grew from there.

Most people forget that Steve was an aesthetic, learnt calligraphy and spent time in communes in India. He was the primary customer for every new Apple product. That is, he was scratching his own itch. He was infamous for calling work in progress SH*T which enticed staff to stretch their abilities and accomplish the impossible.
