<i>Kurzweil's predictions relate to the level of computational power for a given cost and what we can do with that power.</i><p>Indeed they do. And there's an order of magnitude separating the computational power and cost of iPods from what we can currently incorporate into reasonably priced clothing. A friend of mine does research in the area of wearable computing. We're not at the iPod-in-shirt level yet.<p>Further, if we don't hold predictions to what they actually said, then there's no point. We can always manufacture an interpretation in which the prediction is true.
