From an interesting piece by Max Fisher:

We think of any danger as coming from misuse — scammers, hackers, state-sponsored misinformation — but we’re starting to understand the risks that come from these platforms working exactly as designed. Facebook, YouTube and others use algorithms to identify and promote content that will keep us engaged, which turns out to amplify some of our worst impulses.

Even after reporting with Amanda Taub on algorithm-driven violence in Germany and Sri Lanka, I didn’t quite appreciate this until I turned on Facebook push alerts this summer. Right away, virtually every gadget I owned started blowing up with multiple daily alerts urging me to check in on my ex, even if she hadn’t posted anything. I’d stayed away from her page for months specifically to avoid training Facebook to show me her posts. Yet somehow the algorithm had correctly identified this as the thing likeliest to make me click, then followed me across continents to ensure that I did.

It made me think of the old “Terminator” movies, except instead of a killer robot sent to find Sarah Connor, it’s a sophisticated set of programs ruthlessly pursuing our attention. And exploiting our most human frailties to do it.
