     Quoth Wikitedium:

	According to CSIRO, in the next decade, astronomers expect to
	be processing 10 petabytes of data every hour from the Square
	Kilometre Array (SKA) telescope. The array is thus expected to
	generate approximately one exabyte every four days of
	operation. According to IBM, the new SKA telescope initiative
	will generate over an exabyte of data every day.

The same article has other rather startling estimates of present-day
data capacities and rates.  Some appear to contradict each other, by
as much as 1-1.5 decimal orders of magnitude, but the overall burden
is clear: "64 bits" is not a synonym for "forever."
