I'm not saying we should all ditch them now. We unfortunately couldn't live so well if we ditch them overnight. I'n just saying we should know what they truly are and avoid any manipulation from them. For example, suppose you get to pick up an opinion from watching social media posts (which is unfortunately not entirely avoidable as long as we use them). Is the opinion solely yours or de facto given by them? Knowing what social media is will detemine the confidence your answer to this question.
