Excerpt from this article:
…In a capitalist economy, the market rewards things that are rare and valuable. Social media use is decidedly not rare or valuable. Any 16-year-old with a smartphone can invent a hashtag or repost a viral article. The idea that if you engage in enough of this low-value activity, it will somehow add up to something of high value in your career is the same dubious alchemy that forms the core of most snake oil and flimflam in business.
…A common response to my social media skepticism is the idea that using these services “can’t hurt.” In addition to honing skills and producing things that are valuable, my critics note, why not also expose yourself to the opportunities and connections that social media can generate? I have two objections to this line of thinking.
First, interesting opportunities and useful connections are not as scarce as social media proponents claim. In my own professional life, for example, as I improved my standing as an academic and a writer, I began receiving more interesting opportunities than I could handle. I currently have filters on my website aimed at reducing, not increasing, the number of offers and introductions I receive.
…My second objection concerns the idea that social media is harmless. Consider that the ability to concentrate without distraction on hard tasks is becoming increasingly valuable in an increasingly complicated economy. Social media weakens this skill because it’s engineered to be addictive. The more you use social media in the way it’s designed to be used — persistently throughout your waking hours — the more your brain learns to crave a quick hit of stimulus at the slightest hint of boredom.
