Both are desperately waiting for the messiah battery to happen. People like the original author seem to face immense difficulty at wrapping their head around the fact that battery technology does not follow Moore's Law (while even chips have mostly stopped to do so). State of the art battery technology has not improved much this side of the millennium, it has just seen a really big price drop from specialist niche technology to commodity. This makes the battery of a Tesla S a lot more affordable today than it would have been back when Musk started the project (and when he correctly predicted a price drop, and just a price drop, instead of waiting for the miracle battery to happen), but the range would not have been much worse if you built a Tesla around a battery made of crazy expensive y2k cells.
