I'm not trying to sound naive here when I say:
their content delivery/ranking algorithms prioritize (from my understanding as just a general person in the public who has never seen what's probably millions of lines of code across many different internal private systems at Meta) user engagement over all
If the algorithm is spitting out content that we're all critical of (because it's divisive, bad for mental health, etc.), why are we not acknowledging that it's just a side effect of
1. user input + 2. user engagement to that input = 3. ranked content delivery algorithm
If Facebook went away tomorrow, another platform would fill its place. Humans have shown that they like to doom-scroll on their phone and are ok being fed ads in the mean time because social media scrolling is basically the equivalent of an electronic cigarette for the brain in terms of dopamine delivery.
Because humans have chosen to prioritize the shittier meanier grossier nastier content, Facebook's "models" have been trained on that. Why are we criticizing Facebook's models that we basically played our own individual role in building?
