This guy makes the assumption that all problems are big problems.
Most problems are NOT big problems.

Data is getting bigger, sure. Movies in HD, umpteen-megapixel cameras, yadda yadda in the consumer space, but hardware is getting bigger too, for the same price. You can easily buy a terabyte drive now. My first HD was 20M and I thought I'd never need anywhere near that much!
But in the corporate space - where is this data actually coming from? If you have a company selling widgets, then by how many orders of magnitude do your sales have to increase before you have to worry about "big data"? Most companies could probably handle a tenfold increase in sales on their existing systems, even if those systems haven't been updated in a few years. Bread and butter software work is not going to change in the foreseeable future, it'll just have a different set of buzzwords.
In business I see lots of folks who do this: "Well, if I do what XYZ does, I'll be successful just like they are!" So they do what XYZ does without understanding the WHY part of what XYZ does, and invariable either fail, or succeed and making a very poor copy.
As problem spaces expand beyond our current hardwares ability, we start distributing it until a new wave of equipment becomes available and we start labeling our predecessors idiots for having ever built something so complex.
