So. This is funny. I actually work at Goldman, work in the system he talks about, and have been doing so for 5 years. You can get numbed by the experience of working here, but you don't have to be. I've become friendly with some of the best hackers I know, and for us, finance always takes a backseat to writing amazing code. Sometimes we succeed. Sometimes we fail, but we try to never say, "Meh. Good enough."

Wall Street is like any other business. Don't over-glorify working for Google and not Goldman: tech companies are in it for money too; so are startups. At least on Wall Street people tell you they're doing it for the money. It's easier to detach that way and remember that what you're doing is just a job.
