The demoscene still exists, although it doesn't seem to attain a lot of new members, and most (not all!) of the activity is back on oldschool platforms like Amiga or similar. See e.g. https://www.pouet.net/; Assembly 2026 is this weekend, so there's likely to be new interesting releases coming out.
Social media does not only spread bad ideas, but degrades the symbolic machinery people use to form ideas in the first place. It trains reflexes where thought should be. There is no symbolic lattice for things to land and it turns people into reactive zombies.
I suppose the issue is that they will simply ask their LLM to summarize and to reply, so if anything, it might just normalize and justify it a bit more.
Everyone has some economic game going on. If some entity can see most of the cards you hold, it like putting your cards open on the table during a poker game. That is why big companies want your data, they want to peek at the cards of as much players in the game as possible.
Information asymmetry has always been a thing, wars have been though over this.
But I think that in our age, information asymmetry is particularly low, at least in western countries. Each one of us has access to a tremendous amount of data, sure the powerful have access to more, but I have a feeling that the relative difference is shrinking.
I will always remember when a police investigator was interviewed, the context was a controversy about police files. The investigator said: "police files? not very useful, when we want to investigate someone, we browse Facebook". It means that the police doesn't have much as much of an information advantage compared to you and me.
Journalism, world events, etc... Most of the times, we have all sorts of first hand reports, photos, videos, news sources from enemy countries, etc... Not all of them reliable, and factchecking enough to see through that mess takes work, but it is possible in a way that wasn't before. A lot is available on open data platforms, plus all the shady stuff like Wikileaks, darknets, etc... that are not that hard to access either.
Should you want to, you can be your own Palantir, because most of what Palantir does is standard data analysis that can be done with open source tools, and most of the data sources are public, private data is just the cherry on top.
Of course it takes work, but it is possible with limited resources, mostly a computer, an internet connection, and time. No need to travel around the world to meet contacts and get access to paper archives.
