Martine Rothblatt: My daughter, my wife, our robot, and the quest for immortality

The founder of Sirius XM satellite radio, Martine Rothblatt now heads up a drug company that makes life-saving medicines for rare diseases (including one drug that saved her own daughter's life). Meanwhile she is working to preserve the consciousness of the woman she loves in a digital file ... and a companion robot. In an onstage conversation with TED's Chris Anderson, Rothblatt shares her powerful story of love, identity, creativity, and limitless possibility.
