Long time geek, fangirl, mother, and reader. I've got a lot to say, you might not like it all, but it will be honest and hopefully helpful.
Such a good, gross, point about potential ethical issues created by placing robots/androids in human social positions. Personally, I feel using child robots to help pedophiles would not only unethical treatment of robots, but also it doesn't actually cure the behavior. It just gives them a different kind of victim. Much like methadone doesn't cure addiction it just gives the addict a different drug to use.
