I think when robotic sex toys become advanced enough to replace real people we are in trouble. That means that robots will be advanced enough to do almost anything. Why would anyone want to employ a human when they can just employ a robot? No one will have work, humans will become useless to the economy and civilization will fall. This is far more serious than something that will effect the sexual market place. Replacing people with highly advanced robots is very dangerous territory. Robots don't need to eat or drink and robots are not conscious. Robots don't need to sleep and can work endlessly and they don't need to be paid a wage. Think about it. This worries me the most and should be worrying everyone else.
