That's a very narrow view of information in the academic/research world.
Contrast with
"The Large Hadron Collider will produce roughly 15 petabytes (15 million
gigabytes) of data annually"

I believe climate science, astronomy and genomics experiments will often
kick out a terabyte of data before you've got your lab book and pencil
ready to start jotting it down :-)
