Reading more of stolen focus and its actually insane what the tech companies are doing. Basically, they want to hack your attention, and as we all know is a quirk of human nature we stay focused more if we're angry.
So they feed us lots of it, and then we spend even more time on these sites either digesting more rage inducing algorithms or arguing about it, failing to find any common ground and disappearing down more and more rabbit holes.
I'm sure most readers on here are somewhat aware of this, and I'm probably not doing it justice here but the author paints a scarey picture. These companies know it too, but their business model depends on you focusing more and more on their products, so they continue doing it.
Lots of them don't let their own kids on the sites they design.
