The point was that not everyone needs or has big data. That's hardly controversial. Even some instances where you think you have big data that you think needs to be handled in parallel by a cluster could easily be handled by a single server or even laptop. Again, nothing controversial.

The most important thing is knowing what data you have, how best to collect it, and what it can (and can't) tell you. Just because you find correlations doesn't mean that they are real. It takes people with real expertise to help here, and just running your data on a cluster isn't going to help you. In fact, it could even hurt.

I didn't see anything wrong with the article at all.
