But even quants are not immune to the feeling that what they're doing for a living is not adding up to anything.
Not sure about this, but isn't the quants who are responsible for developing new pricing models for some esoteric options, new algos to capture the fleeting abnormalities in the market , improving (say) the existing Gauss Copula method that so that 2007 subprime crisis could be predicted or being avoided altogether (http://www.wired.com/techbiz/it/magazine/17-03/wp_quant) and so on.How can you say that kind of work is unsatisfying and lacking of creativity?
