I liked that little video. It made a lot of sense. We are a species who must have some slave labor, even if it is robots in the future. We don't have to be that way. Whatever happened to good old fashioned work ethic? Know what I mean? I don't know. It seems the whole human race is one big fat, gelatinous blob, awaiting some anhilation from another planet, so they don't have to do it themselves. Sorry, but it won't be that humky dory. Have you seen the movie Wall-E? It is an eye opening movie. Watch it.
