> Sweating to make a big number get a bit bigger isn't good for the soul in the long term.
I've been working as a programmer for the last 5-6 years, and I strongly disagree.
Pixar, Google and Two Sigma, and many similar companies in these industries, are ultimately absolutely pointless and empty. Entertainment (distraction), ads (mind pollution), and arbitrage (stealing) is essentially what they do. Working for any of them will become mind-numbingly boring and damaging to the soul very soon.
There are only two things that keep me motivated; (1) hard problems, and (2) money. (1) are hard to come by, most of my time I spend dealing with stupid problems caused by stupid people. (2) is why I work on pointless problems, the more I earn the sooner I can retire to do something actually useful.
Therefore, I think that working for a hedge fund in a money-generating role can do wonders to one's motivation; the better you are, the more you earn. Not many roles, in general and in software development, offer such direct payoff.
