Data is replicable, but any data set large enough to be globally useful has a time bounding function. A snapshot of the whole world today is worth less than perfect information just about how humans drive over 200 years / 1.752e+6 hours of observation. Don't you think?

Sure. But that doesn't have anything to do with my comment.

As information goes, [A, B] is more valuable than [A], and the value of [A] declines with how many people/companies have A.
