To be fair, you
can just ignore TicToc.
Okay... maybe you can't. Maybe there are people in your life that won't let you forget it exists. Maybe your job is in communications and you have to get on TicToc (or YouTube or InstaGram or whatever.)
170 million people is about half the U.S. population. And I can't say this without sounding like an elitist pr*k, but it's always seemed like about half the population is below average. (And since we're all savvy consumers of statistics here, we all know that attempt at a joke would be better if I said "half the population is below the median.")
So assuming an algorithmic dopamine-stroking video platform is a social evil, maybe people are susceptible to it because there's something missing in their lives? I don't watch a lot of TV and look at the internet mostly through a text based browser. Mostly because I KNOW I have attention problems. I don't need flashy ads bombarding me with distractions. But mostly it's because I do a lot of other things that aren't watching videos that are more fulfilling (like commenting on HN threads.)
I don't know if this is true... but I like to play the game where you think about how the world would have to change for various statements to become true. (It's fun to wallow in the swampy mud-bath of your own imagination.) What if... TicToc (and YouTube and Facebook and Twitter and all the other attention sucking apps) are a net benefit to people's lives?
I know it's en vogue to bash new media dealers and clutch our collective pearls. But if traditional media could get these engagement numbers, I can't imagine they wouldn't. Walter Cronkite and Edward R. Murrow have been dead for decades. If, as a culture, we valued the Children's Television Workshop, we would have funded them publicly instead of letting them crawl into (financial) bed with NBC/Universal and Warner Brothers.
So sure... maybe TicToc is evil, but what alternative are we offering the half of society that wants their midbrain stroked?
