Why did “big data” come up now in particular? Well, in the last decade
processor speed leveled off, but the exponential improvements in data
storage capacity and transmission rate continued. So we kept on growing
our data volume but we could no longer handle it with one computer,
and the resulting painful rethink of how to do data analysis called for
a painful new buzzword.
Looking at headroom, the next curve to level off should be the data
transmission rate. The buzzword will become something dull like “old
data” and we’ll have to do actual work to snow our bosses again.
Transistors no longer get faster when, following Moore’s Law, they
become smaller. “Big data” is only one consequence.
