In the future, every human will have a digital model of their body stored in computers. When someone needs a new shoe or a new bra or a new prosthesis or a new brace, s/he'll just fabricate it from the digital model themselves and then the device or article will be delivered to the home without even having to go to a retail store. The shoe, the bra, the brace, it'll be the person's apparel, the person's device, no one else's. It'll be exquisitely comfortable and functional. So this whole notion today where we have sizing to fit across humans is just utterly absurd.
