I often hear the phrase, “If I have more information, I can make better decisions.“
Technology has reached a point where getting “more information” is cheap. What you do with that information to “make better decisions” is a different subject.
You can go to Kaggle.com, search for “Wines,” and download the Wine Reviews dataset in CSV format. With a simple Python script like this one, you can get the average points of wines between Italy and Argentina.
What do you do with this information? If Daniel Kahneman is right in his book “Thinking, Fast and Slow,” if you don’t know anything about the wine industry, you are probably making the wrong decision, even with the information.
Pick an industry you know, define the problem you want to solve, and only then leverage technology.
