Abstract
The Roman sage Marcus Aurelius said we should never let the future disturb us. But then he never had a conversation with the futurologist Nick Bostrom about the state of the world in 2050. "There's a good likelihood that by 2050, all scientific research will be done by superintelligent AI rather than human researchers," Bostrom said in an e-mail. "Some humans might doscienceasa hobby, butthey wouldn't be making any useful contributions." Time to rethink your career options. Nature readers!
