<human>:  Why is it that the field of Data science is so young?
<bot>: The field of Data science is young because it’s a relatively new field. It’s only been around since the late 1990s. Before that, data was just data. It was just numbers. But now, data is being used to make decisions. Data scientists are using data to make decisions about how to run a business, how to design a product, and how to make decisions about how to treat patients.
