"So if you're a CS major and you want to start a startup, instead of taking a class on entrepreneurship you're better off taking a class on, say, genetics. Or better still, go work for a biotech company. CS majors normally get summer jobs at computer hardware or software companies. But if you want to find startup ideas, you might do better to get a summer job in some unrelated field. "

As a third-year CS major in college with a couple of software internships under my belt, including one at Google, I'm thinking right now about which industries would be the best to dip a toe in and see where they could use some help from ideas from the tech world. One area that's clearly been exploding is bioinformatics - I've spent some time at a lab doing research in the area, and it's an interesting field. What are some other ones that people might not immediately think about?
