> Decentralization is better termed "de-professionalization." The institutions which used to, at the very least, dedicate serious resources to going out into the world and gathering facts no longer function properly or just don't exist.
But now the people they were gathering the facts from are connected to the internet.
Local newspapers often had a police blotter publishing the police reports in the locality. Now you can get that directly from the police department, because they have a website.
Once upon a time if you wanted to get stories from Turkey and Israel and Brazil then you had to send reporters to those places to collect the stories of the people there. Now the people there are on the internet and can post their stories themselves.
You're getting closer to the sources instead of having a "professional" as an intermediary. But you're also getting access to more sources, with more differing opinions, and it's driving people nuts because they don't know who to believe. But there weren't any fewer sources before, you just weren't hearing from so many of them because the traditional gatekeepers decided for you what you got to hear. If you assume they were doing a good job of that then we've lost something, but what evidence is there of that?
