Social media is literally just a fairly accurate reflection of us as a species and our civilization.
Strong disagree. Capitalists sell it to us as a mirror, but it's a distorted mirror that shows us exactly what they want us to see for whatever reason.
If they want to sell us diet pills, they will turn it into one of those amusement park mirrors that makes you look fat. If they want to overthrow democracy, they'll turn it into a mirror where everyone standing around you suddenly look suspicious and cruel. And if the Russians want to pay them to get control of what people will see in the mirror, hell - that's just freedom of expression.
Add on top that pretty much everyone on earth is staring mindlessly into the mirror for hours every day, and you got yourself what I would consider to be a problem.
Social media is probably the most powerful propaganda tool of all times.
In the 1960s you would say the same thing about TV, and you'd be right. Before that it was the cinema. It's not because the mediums as such are inherently evil, but they carry an inherent power that can be used for evil.
Currently, social media is very much being used for evil.
There is, however, another element to it, and one that is completely new for social media. That's the illusion that we can actually contribute in a meaningful way by participating.
Nobody believes they are actively fighting fascism by watching TV all day. Yet, on social media, well-meaning people are wasting their time shouting at clouds rather than going out in the real world and and actually achieve anything. They collectively tread in water as democracy dies, all the while they feel like they are "doing their part". In other words, social media is pacifying as fuck.
I participate in the Fediverse because I have hope that we are building something different here; something that can derail the platforms that are currently used for evil, and something where the organization of actual opposition can be possible. I think it might be. But I am also afraid I am just wasting my time.
