It was a blind spot that I had until my senior year of college, when I realized that I wanted to make a lot of money, and that it was very unlikely that majoring in philosophy would let me do so. Had I realized this at 12-14, I would've saved myself a lot of time; but I didn't, so I'm probably going to have to go back for another degree.

If you don't care about money or you have the connections to succeed with a non-STEM degree, that's another thing. But that's not the question that was asked.
