There are some things that some people can solve in a given time frame, which other people could never solve. For example, could you have ever invented calculus or discovered relativity? What about someone less smart than you? That's an even more extreme example than the one given. Moving back to programming, debugging specifically, I've had people spend weeks stuck on a bug, only for another programmer to find it in hours or days.
