I like Elon to buy and kill Tiktok next. Then he can move to Facebook. As far as I can tell. The death of social-media platforms is a major positive for society as a whole.
The death of one social media platform hasn't been the death of social media since the days that MySpace killed GeoCities rings and Facebook killed MySpace. The difference is that, this time, people will have one clear-cut event that occurred to point at as the moment in time that something else got the opening to make a play for Twitter's marketshare and the single event that prevented Twitter from being able to prevent it.
That event is, in case there's any doubt at all in anyone's minds, is Musk.
