If I had to choose between two robotsOne that looks real, and might possibly have the entire encyclopedia and knowledge of most things in its head, and could teach my kids to learn a new language, and so on and so on, that sits on a couch and becomes a part of the family. Or have another robot that vacuums, cleans and does house work. I'd go with the smarter one. If these robots are designed to do work, and make vital mistakes, even if a speck of dust covers it's vision scanning, it could possibly burn a house down. And I doubt insurance co's will cover that. Lot's to think about. I like Realbotix's odds of success. Jmo. Dyodd. And GLTA;).
