>Nothing works like that. Sure. Thrown in another order of magnitude in to account for that. Heck, throw in two! Why not say that a single 4GhZ CPU core today has a processing power of 100 4GhZ CPU's of yore. You're still orders of magnitude behind the growth of disk space. And that only makes sense for very simple and fast algorithms. Anything super-linear is still very hard with the amounts of data we are able to collect. Which is the author's point.
