I remember sitting in his back yard in his garden one day, and he started talking about God. He said, ‘Sometimes I don’t. It’s 50-50. But ever since I’ve had cancer I’ve been thinking about it more, and I find myself believing a bit more. Maybe that’s because I want to believe in an afterlife, that when you die it doesn’t just all disappear. The wisdom you’ve accumulated, somehow it just lives on.’ But then he paused for a second and he said, 'Yeah but sometimes I think it’s like an on-off switch. Click, and you’re gone,’ he said. Paused again and said, 'And that’s why I don’t put on-off switches on Apple devices.’
