Neil Postman (of whom I'm a big fan, to put my cards on the table) wrote very helpfully about the concept of "filters" (that may not be his word) in Technopoly, and I've been thinking about the concept a lot ever since. Certain things are inadmissable in court, and that is true because otherwise you'll just have bedlam. The analogy doesn't hold perfectly, but the same thing is true of other situations where people gather together to communicate, whether in person or online.
The other thing that's required to avoid total chaos is authority, and I think it's a common trait to be dismissive of the value and purpose of authority in this context. People have been dismissive about authority since, uh, forever, but I think there's something about the promise of the internet that makes people think we have finally arrived at the point where it is unnecessary. (Think blockchains and crypto, for instance.) But it's not.
The sooner we see that authority isn't a bug but a feature and begin to build for it in our tech tools, the better.
