If this same "study" had been conducted 40 years ago the results would have been massively different because back then storage technologies were in their infancy. Assuming a similar trend continues into the future, the extrapolations presented in this article are as rational as saying that we'll need 7 billion horses in order to ensure everyone has personal mobility. Technologies improve and do more with less. Next mistake, the article also assumes all data is eternal. Sure it is. Anyone remember any doc they created in WordStar? Or their MySpace page? The fact is, a huge amount of data vanishes quite quickly; only a relatively small percentage persists over more than a few years (and this is influenced by legal retention requirements in most cases). So the tsunami of "heavy data" the article imagines is wildly wrong, as are most "predictions" about the future, and always for the same obvious reasons.
