It's not as if it's either/or. Clearly it is true that new technologies -- say, for example, the telephone -- affect our social lives. Consequently, abstaining, for whatever reason, from using those technologies will affect your social life. To what degree and in what manner totally depends on the individual involved, the technology itself, the way it is being used, etc.
However, one thing is certain, I think. Some technologies may have a transformative effect: The fact that you could act in manner X to get result Y before the technology gained widespread use does not mean you can continue to do so after it has. I'm sure this was true for the telephone, and I'm pretty sure it's true for Facebook and its replacements.
