I somewhat agree, yes, we cannot imagine our lives without social media anymore. This is where we get our everyday news, talk to family and friends etc... but then again, could it be replaced? I think yes, I don't know with what yet, but as everything is being developed so fast I think soon we will have a totally different understanding of social media than we do at this very moment. There's been so much talk about how Facebook is dying etc... that probably means that people are craving for new solutions and where there is demand there will be a solution.
