I'm not a physicist, but a physics drop-out. However, I am still in touch with many of the people I studied with. Only a few stayed in physics in the end. One thing I noticed is that because physics has multiple decades more experience with dealing with big data compared to just about every other scientific field, a lot of physicists who jump ship tend to end up in a position where they can apply that expertise. I worked as a programmer for a molecular neurobiology research group for two years. Biology is going through a kind of Cambrian explosion of new data (especially when it comes to anything that involves genetics). So it's probably not surprising that a number of people at work told me that it is extremely common to see physicists switch to biology because that's where all the exciting new research is happening, with new theories and discoveries, and lots of people who are very happy to steal whatever the physicists have already figured out about how to process and interpret mountains of data.
