Well, do what all the 'cool kids' are doing in physics: comp-sci, neuroscience, and finance. Seriously though, the 'heroic' physicists out there are moving to other fields and are doing very well. They are smart people, and they can see that most of physics is stuck in a rut until a massive increase in funding comes along or some kid gets really lucky with the math. Neuro and the bio fields are getting shook up with the incoming physicists around, the nanoscope revolution has been kicking for about a decade. Finance has had quants for a while, but a pipeline to Wall Street is starting to emerge in force recently. Comp-sci has always been inundated with physics undergrads and PhDs, and we see the result in Silicon Valley's wealth.
