Same were the fears when computers got started in our daily lives in early 80s. However, computers ended up creating many more jobs than they took. Same might be true with robots. Many new industries and products might prop up as a result of high automation in the society.
When it gets to the point that computers can do everything some humans can do, but better, faster, and with fewer mistakes...then, I suspect, computers will start taking more jobs than they produce. Honestly, I look forward to that point. I like that my dish washer takes care of one of my chores and leaves me with less work to do. There will always be more work to do.
