I think about this a lot: you’re young, you come from a smart, wealthy family, you’re somehow supposed to show that you’re successful quite quickly. Banking, law, consultancy allow you to do this; engineering, science and entrepreneurship less so. Your friends expect it, your parents, your potential mates do ... So we see so many talented people very quickly having to signal how smart they are but that may not be the longest-term social productivity.
