I think that, as always, the important is the implementation. People are mentioning Facebook's attempts to check fake news as an example of how this is a bad idea, but Facebook is a system that has trained hundreds of millions to just thing in terms of "thumbs up/ thumbs down". Wikipedia would be a better example of a collaborative system meant to distill some shared truth out of the work of faceless crowds, and while it has serious issues, it's also been a remarkable success. And Wikipedia basically lacks tools for structured discussion, and the bureaucratic processes in place seem all built on on the most basic hypertext technology. Let's not underestimate Musk's logical thinking and ability in executing.
