Or they could just wait for Pandora to go under, and bank on the prospect of picking up some of its users eventually anyway, without having to pay anything at all.

In a 2011 interview with The Guardian, Hawking addressed how he feels about his own mortality. "I have lived with the prospect of an early death for the last 49 years," he said. "I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first."
