In the US. Undergrad degree included CS. Spent a few years in software engineering industry. Left industry to pursue a PhD in computational science. Returned to industry right after completing the degree. At a hedge fund for 4+ years now. Dunno if that counts as "switching". Anyway... I love it. Interesting problems with demonstrable business impact when you find a good solution. Software in an environment where robustness can be critical but, too, overpolishing work can be full of opportunity cost. A chance to keep reading/using academic literature. I hit a conference about once a year. Great coworkers from a myriad of backgrounds. I can afford to have a family, to spend time with that family, to give them a nice quality of life, and to save for the future. I have been lucky/blessed/etc.
