I think Joe Orez's reply (from 10 years ago!!!) still makes sense. P&C actuaries will be working on things like insurance and insurance implications for driverless cars, drones, cyber liability, climate change and a seemingly unlimited list of new kinds of risks. Life and health actuaries will be working on (yawn) life and health. Which of the two branches of actuarial work seemd more interesting now, and in the future?
