Well, maybe. We just don't know how things would have played out. The safest assumption seems to be that people like Steve Jobs and Steve Wozniak very significantly accelerated progress. But because of the way acceleration seems to kick of revolutionary changes, it does seem fair to say they were pretty 'Great' in terms of their impact. For example, without them, maybe we would be in the 1990s era of personal computing now, thirty years later. Or maybe someone else would have done even better than them, and we would be further along, but the latter is harder to believe. We'll simply never know the answer to these questions because we can't run the counter-factual.
