Bill Gates: Try a career in artificial intelligence, energy or bioscience to make an impact

Congratulations! You've just accomplished something I never managed to do-earn a college degree. Between your commencement speaker and every aunt and uncle at your graduation party, I am sure you are getting a lot of advice. At the risk of piling on, I thought I would share a few thoughts. New college graduates often ask me for career advice. I was lucky to be in my early 20s when the digital revolution was just getting under way, and Paul Allen and I had the chance to help shape it.
