I want a computer that’s as flat as a pancake and can be rolled up, just like a newspaper. I want a 3D television as wide as my house, and free implants, behind the eyes. Ziiiing. I want a cellphone that’s powered by the sun, and calls my grandfather in the asteroid belt even though he’s dead and I never knew him, although I know of him from stories, photos and my mother. But I want to know his music.
