It's very clever. It redirects of a raft of points Wong makes into a narrative Musk is pushing. It probably represents one of the reasons why he's so successful. :)

It also loses its luster on a bit of reflection -- this particular novella was in fact published on Twitter, and obviously got plenty of attention, including from Musk, so it's not exactly clear that Twitter's an unacceptable venue for novellas. Also, there's other long-form platforms that don't seem to have competed well with Twitter so far.

But maybe someone could pull off making such a thing work. Which is why personally what I'd like to see Musk do is take the assets he was going to use to purchase Twitter and build another platform, one with the features and values he's envisioning from the ground up. He might have the juice to pull it off, and it would help diversify the media landscape and discourse culture rather than just being a tug-of-war.
