"It's strange to think that you accumulate all this experience, and maybe a little wisdom, and it just goes away"

 "I am about fifty-fifty on believing in God. For most of my life, I've felt that there must be more to our existence than meets the eye …. I'd like to think that something survives after you die. It's strange to think that you accumulate all this experience, and maybe a little wisdom, and it just goes away. So I really want to believe that something survives, that maybe your consciousness endures. But on the other hand, perhaps it's like an on-off switch. Click! And you're gone. Maybe that's why I never like to put on-off switches on Apple devices."
