Why doesn't someone invent clothing with very small, powerful magnetic material woven in? That way all the clothes teenagers leave strewn about the house could be automatically pulled toward a designated laundry basket. Or what about a central trash system, like central plumbing, where all refuse gets whisked away to some underground recycling facility inhabited only by the alligators of urban mythology. Someone should definitely invent that, too. These technologies would make our personal lives easier.
