It really boils down to balance, doesn't it?  Most people can see the positive impact of self-driving cars:  eliminate most accidents, allow people to use the time they would have used for driving for some other purpose, etc.  But do you want a robot to hold your child and sing him/her to sleep and subplant that essential human connection?  Probably not.  We will need to get better at assessing the long-term cost-benefits of technology in our lives.  Right now, many people don't really understand or care about what they are giving up in order to acquire convenience or efficiency.  People need purpose and meaning in their lives or life has no point.  Technology cannot give us those; they must come from within.
