Re: I'm having a vague flashback here...
Given that there are estimates that each person will be producing 5Tb of data/year by 2020
People make all sorts of claims (sometimes in passive voice, to avoid attributing them). I suspect anyone promulgating such an "estimate" is a tad hard of thinking.
What is it even supposed to mean? What constitutes "producing data" in this context? How much of that data is said person going to want to store? Will this same amount be true of both some techophilic wannabe-transhumanist lifeblogger and a subsistence farmer in Bangladesh, or is "each person" the sort of handwaving rubbish thrown around by pundits who can't be troubled with the details?
And why 5Tb? Because it sounds better than 0.6TB?
