You are too quick to close this big door here. You could do them relatively "ugly" and "difficult to use" if you'd do a driverless cars, a plane with real beds, a self-backuped unlimited size hard-drive for music and movies, a viable water desalinisator, a cheap enough 3D printer, a bodyless computer monitor, or even a working dating site.

Not that I disagree with the rest, but let's not say everything is done already and just needs to be done better.
