Cathy "Mathbabe" O'Neil is a former finance-industry quantitative analyst who escaped her former career and has advice for other quants looking to do something better with their lives. She works in a startup now, and offers a fascinating study of the contrasts between finance culture and startup culture:
First, I want to say it’s frustrating how risk-averse the culture in finance is. I know, it’s strange to hear that, but compared to working in a start-up, I found the culture and people in finance to be way more risk-averse in the sense of personal risk, not in the sense of “putting other people’s money at risk”.
People in start-ups are optimistic about the future, ready for the big pay-out that may never come, whereas the people in finance are ready for the world to melt down and are trying to collect enough food before it happens. I don’t know which is more accurate but it’s definitely more fun to be around optimists. Young people get old quickly in finance.
Second the money is just crazy. People seriously get caught up in a world where they can’t see themselves accepting less than $400K per year. I don’t think they could wean themselves off the finance teat unless the milk dried up.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
