It's the newbie who does something he didn't know was supposed to be impossible. It's the naive guy asking the one dumb question any clued-in person would diss. And it's that question that leads to the answer no expert would have found.
The clueless accomplish amazing things -- not necessarily because we're bold, brilliant innovators, but perhaps because we just don't know any better. We see the simplicity of the forest while Those Who Know are overanalyzing the complex subtleties of the trees (and miss the point). Sometimes NOT knowing about a "problem" weakens (or eliminates) it.
Perception is a powerful tool. Believing there's a limitation can sometimes create that limitation. And for the clueless who don't know about the limitation, well, it's as if it doesn't exist. Belief matters. Not everywhere, not in everything, but more than we give credence to.
