Yes, I am apathetical because it seems self evident to me that the reason Jobs invented the smart phone and I never could is because he's smarter than me. I guess I call that humility.
Perhaps the point of the quote is to encourage people to falsely over-estimate their own smartness in order to maximise the likelihood they'll try to make a difference - because a tiny percentage actually will.
The right question would be:
"Would you have been able to invent the smartphone if you had made the same experiences and insights as Jobs did"?
Because, a lot of people like jobs had similar experiences in the early days, e.g. Palo Alto Research Lab around them - though, it was Jobs who came up with the idea, not any other of the SC veterans :)
Whether some people really were "smarter" than you (whatever that means) is not relevant to the point of the Jobs quote, I think.
