"When you think about it, there's no way to input things into a computer. It's all... the holes only go out, right? Like you can plug a keyboard or a mouse in but that's a trick because the computer thinks the inputs are outputs. That's a programmer trick, basically magic. The key to the future is to make holes that go in too."

Children long to know that they are lovable. And there are ways that technology can help with that. But ultimately it's their relationships with their parents, their grandparents, their peers, and their teachers that help them to know that for sure. A child can learn the word "hug" and the letters h-u-g through a computer, but a computer can never give the child a hug.
