I agree with the sentiment that algorithms do affect what we see in our feeds and often the things we see are chosen because they are deemed more engaging by said algorithm, but I also think we're overstating the effects of the algorithms and putting too much blame on them. I think we need to recognize that the technology we've built is inherently addictive and also making human connections more impersonal.
If you took away the algorithms, I don't think you'd necessarily have a relaxing social media feed. You'd still have people sharing so-called "engaging" material and you'd still have to deal with "context collapse" and disagreeable discussions. I think the anonymous nature of online connections inherently make them more impersonal compared with actual face to face ones. And being constantly connected to other human beings digitally (even strangers) is incredibly addictive.
