Earlier quoted context omitted.
Even without political advertising, the amount of fake news spread in Groups in the form of memes and images is absolutely fracking staggering. If you go through the facebook feed of a conservative facebook user in their 50s+, you quite literally will see all lies and propaganda, and nothing real (for one ex: see the horribly faked Nancy Pelosi video that spread like wildfire yesterday, despite it's obvious fakeness)…
Do you think any other platforms are doing better, or is all social media inherently doomed?
It's not "social media" which is doomed, but it's our systems of government. China does just fine with controlled social media that is heavily censored precisely as the government wishes. It's not social media which is doomed, it's democracy, because authoritarians can exert power and control.
It reminds me of the Paradox of Tolerance. [1]
So long as social networks (and we as a society) tolerance this anti-intellectualism and choose fake news over real news, real information can never flourish.
But what can you do? Pass laws (which explicitly violate our American 1st Amendment)? Wait on Facebook to fix one of their biggest engagement (read: profit) drivers? Or just let everything come crashing down and shrug?
Who knows. The answer is aggressive moderation and banning fake news. Recreating the culture of intellectualism and truth. Emphasizing critical thinking. But I am extremely pessimistic that anything will (or even can) be done.
We're in meme-fueled political quicksand. I don't want to sound defeatist, but maybe after a generation or two passes and the millenials are older, this type of information warfare won't be nearly as effective [2]. Until then... good luck.
