How do you feel about robots becoming part of society in the future?

I was do some research about robots and the plans to add them into society, working as caretakers for older people, waiters, teachers, industry workers, mine workers, prostitutes etc. Robots are being engineered to be more like humans in look and function. Some say 2020 will be the year when robots trully neter mainstream human society. My reference: http://machineslikeus.com/news/potential-future-impact-robots-society.

How do you feel about this – being intimate with a robot, having a house cleaning robot, or competing with robots for jobs, etc? Do you think society would benefit from robots or would we end up like the society in the Martian Chronicles?

Is it possible to take the whole “machines working for us” bit to far?
