It's interesting how Kay's "error-free internet" quote was truncated in this article. Here's a bit more of the quote:

"The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free? The Web, in comparison, is a joke. The Web was done by amateurs."[1]
