Hmm.. I'm sorry but I disagree with your two opinion. Although I agree that people will be lazy by robots, but I don't think using of robots can be dangerous more than other machine. Other machines are also likely to be dangerous at any time. But we live in mechanized society. So do robots. And you say, unemployment rate will be rise as robots  replace people's jobs. But I think it's just a short-term situation. Many new jobs related to robots will be created. So I agree that robots replace people's jobs. I'm sorry and I hope you're not offended. Thanks for reading.
