Catching Robots

Nowadays, AI had become more common, but it is still a new and exciting innovations. I started to think about the robots in the future. If robot became so common and they can do whatever we can and even do things we [human beings] can't, could we be replaced by them? Using robots to do everything seems very convinient to us, however, I really think a huge financial crisis will happens, since humans are replaced by the robots. Robots are built to satisfy our needs and/or wants, so the robots will be made perfectly so that they can perform even better than the professionals. For sure, those of who work pink collar jobs will lose their jobs, and they won't be able to find any another job in a period of time. How are they supposed to survive? Even the profesionals, for example, teachers and professors, will lose their job sooner or later, since all the knowledges are installed into robots brain. Although the robots can make our live easier, I am really worry about the fact that people will be replaced by them. (Or maybe the Earth is polluted badly and the day will never come LOL)
