I think technology has hurt the immediate family but been a boon to the extended family. It is far too easy for families to each be absorbed in their own technology and not talk to each other or do things together. Communication via internet or phone is just not the same as real face to face time.
On the other hand if you have family that lives far away technology is a godsend. We can easily and cheaply talk everyday, we can use things like Skype and face time to see and interact with each other more regularly than geography would normally allow.
The key for me is to use technology to increase your ability to communicate and socialize and be part of life on this planet, not narrow it down to a few words on a page or a few letters in a text.
