A money maker so we don't have to work again?
Or how about something to make hiring easier on the people that do the interviews so we don't hire people that aren't right for the job and we can tell them after reading some sort of brain scans or something. Heck I don't know.
A robot husband, so I'd have someone to cut my grass,and watch my babies while I shop,and be there for me to gripe at! LOL And if I got tired of looking at him,I could pull his plug and stick him in the closet!
