In the case of central/popular social/communication software, this is much, much worse, because it can be set up so that taking up the mindset for resistance directly conflicts with taking up a mindset that will be (or be read as) adequately engaged for relationship maintenance and continued connection; the persuasion can use your friends as an attack reflector, getting mixed up in the signal. And no amount of purely individual willpower will help you not get steamrolled by that so long as you remain dependent on the society around you.
(I want to find an analogy to use for the latter—I'm almost tempted to say it compares to historical examples of ideological spirals the same way nuclear explosives compare to conventional ones, but that feels not-quite-right. History pointers appreciated if anyone has 'em.)
It's not like I'm some superman to notice this stuff. People know they shouldn't scroll IG all day or eat McDonald's for every meal. It might play into subconscious biases but ultimately people are consciously aware of their behaviors in the macro.
What's disingenuous is to think that only smart/savvy people know that the app equivalent of junk food is bad. Personally, I grow really tired of this (seemingly pervasive) viewpoint that the everyman is clueless and helpless and will be totally fucked if we, the learned/savvy, do not intervene. (Apologies in advance if this is not your view - I am complaining about a wider problem more so than replying to your specific comment.)
It's a seductive viewpoint, and one that seems to tickle the "but it's obvious" common sense. I don't think it's true, though, despite being very plausible.
Casinos exist, with way more extensive and battle-tested addiction-response features than the Facebook app, and the vast majority of people in the cities in which they operate don't go broke pouring their life savings into the machines.
Give the everyman some credit.
It is not about stupidity or awareness. It is about finding satisfaction or motivation elsewhere. Educated people, rich people, poor people, ignorant people: all classes have their addictions.
I look forward to the studies that may come in the next generation that examine the outcomes of these apps, app networks, and the mechanisms employed to elicit more user fellowship, and at what cost, both emotionally and physically but also socially. No clue where we go from here, but what's happening now isn't good, and it's hard to see how people actively engaged in it will ever realize the negative effect it is having on our future enough to put a stop to it or at least engage in a discussion around curtailing some of these patterns.
