Robots can generate economic benefits, but the initial capital, such as research and robot production costs, will be too large. In addition to the production costs, operating fuel or management costs will be high. However, I agree with your opinion that instead of putting manpower in danger, you will replace robots. We appreciate the advantage that people's lives can be safely without being threatened in dangerous places such as accident sites to replace it by robot. So I disagree with robots replacing people's jobs, but I highly agree with robots in danger situations like accidents.
