[Music] Allow me to introduce you to Pete. Pete is my Tamagotchi. Some of you may remember these. A Tamagotchi is a kind of simple digital pet you can care for. So with Pete, I need to push specific buttons at specific times to feed him and play with him, generally take care of him. And if I do a good job, Pete can have a long and happy life. And if I do a bad job, Pete could die. And honestly, that would make me sad because I care about this simple piece of technology. If I was giving my talk right now and ...
