robots and hopeless optimists

I think I am a hopeless optimist. I see a future where robots do all the manual labour and for the first time in its history mankind is free from manual labour and left to do the real creative work. But then, when I read in the papers how military/industrial complex is enthusiastically pursuing soldier robots, I understand that I again have been too optimistic about this animal called homo sapiens. Of course, how could I forget, we are first going to use these robots to kill each other, and then will think of better uses for them.
