The funny thing with stuff like this, to me, is that what I want most out of all this stuff is an Optimus / Atlas-style humanoid robot that can be quickly taught to do any number of simple tasks. 

Most people seem freaked out by it, but it seems like the best option by far, because I already have a washing machine, a clothes hamper, closets, dressers, etc. So why can't a robot just use my washing machine while I'm at work, and I come back to the house to find all my clothes folded and put away?

Similarly, such a robot could empty cat litter boxes, do the dishes, sweep and vacuum floors, and maybe even make dog food so we don't have to.

The idea of a utility android is way more interesting than another expensive single-purpose gadget.
