I think he will either do what he can to sell Twitter, or he'll fold entirely.
That sounds pretty dismal, but don't forget one of his first post-ownership posts was the kind of disinformation he said he was trying to end, while promoting free speech. What he retweeted with nasty false insinuations was an outright lie about Paul Pelosi, and he's not even apologized for it. And that's just one thing. I won't belabour HN with another rendition of his well-known dirty laundry list.
It's really hard for me to imagine him getting this one right, because he's flailing so badly in all the predictable ways he would, right off the bat.
