Instagram is actually much worse. FB is not super addictive, at least it wasn't for me. But IG is, and it very clearly has been _designed_ to be that way. It took some effort for me to get off it, and my wife is unable to kick the habit even after I demonstrated to her _with data_ that her Instagram browsing is now a full blown part-time job, and that time could be put to a much better use. TikTok, FWIW, is even more addictive than that, on top of effectively being foreign intelligence spyware. This is being done deliberately much for the same reasons Big Tobacco added stuff to tobacco to make people buy more cigarettes.
There are basically two benefits to social media, in my view:
1. It de-centralizes narrative peddling from just 5 or so people who own all of the media to a much greater number, so it gets harder to "make people believe in absurdities to get them to commit atrocities". I'm sure someone will argue the opposite, but the fact is, if FB existed in early 00s, NYT would not be able to sell us the Iraq war. Ms. Haugen is arguing that the 5 people should regain that capability. I disagree with this very strongly. I'd rather have disinformation from multiple sides rather than from just one - easier to read between the lines that way.
2. It lets families and circles of friends communicate a bit more effectively than, say, an instant messenger would. I think the trend there is actually towards messengers - my friends worldwide basically have our own "feed" in Signal which we do not share with anyone else, and from which messages disappear after 4 weeks. Zuck clearly saw this trend much earlier than most people, hence the acquisition of WhatsApp for an eye popping amount of money.
IG / TikTok are borderline useless in either of those things. They just drive jealousy, depression and mental illness in people since no matter how well off you are your life won't be as exciting as the collage that consists of the best 30 seconds of someone's year. It basically looks like your life sucks and everyone else's doesn't, even though it could very well be the other way around IRL, and things intrinsically seem that way to nearly everyone who uses the product.
As a side note I'm very disappointed that Petapixel chose to participate in what is an obvious and crude political hatchet job.
