Who says dataker's interested? Maybe dataker just wanted to make more money and so chose CS. Or became interested after getting into the field. Why does your choice of major have to be something you're really interested in?
I think part of the issue is we keep selling high schoolers on the idea of "choose what you love", but in high school your breadth of experience is laughably small. Picking a major that would pay well and then approaching it with a good attitude would probably get one farther.
