No, change is not always good.  But you are correct, robotics are coming fast whether we like it or not.  And if folks are worried about Mexicans taking their jobs, they ain't seen nothing yet.  

The workforce is going to look dramatically different in 20 years.  Many of the low-paying and repetitive jobs will be gone - factories and farmers and taxis and McDonalds...  Soldiers too. And pilots.  And probably a lot of doctors and nurses.  

So what jobs should today's kids be preparing for?  Hard to even predict.  Robot repair?  How many of those will we need, especially when robots start repairing themselves?  And who will benefit from that automation?  The people losing their jobs or the people that own the robots? 

The pace of technology is speeding up.  Can our society keep up?
