How did the creator of Apple know that his innovation was going to be successful?
The fact is that Steve Jobs and Steve Wozniak did not know their innovation was going to be successful. According to Wozniak’s autobiography, iWoz, Jobs had the idea to sell the computer as a fully assembled printed circuit board. Wozniak, at first skeptical, was later convinced by Jobs that even if they were not successful they could at least say to their grandkids they had their own company.
