I'm a pretty big fan of data...but this is too extremist. There are plenty of things for which data does nothing and more data does more of nothing. Data only improves your decisions if the past can be helpful in predicting the future, and it only improves your knowledge to the extent that truth is immutable and the data is completely unbiased. And this is all before we get into practical problems where data is messy, unstructured, inaccurate, and still requires intelligent brains to interpret and understand in all of its dimensionality. Sometimes you are just better of with a solid theoretical abstraction, or a good intuition. If you are smart, you will understand that they make great priors that can get better with data. If you take the dogmatic route and only trust data, you will constantly feel like someone else had a head start on you.
