Yes AND he's desperate for approval from those he sees as peers. Twitter enabled things like the Arab spring and was a useful tool for protest organizing and shining a light on horrific things - it was a lot of bullshit too, but it was also that.

The Saudis and other authoritative, fascistic dickheads with billions all over the world benefit from a useless Twitter and the decreased threat that it can be a tool used to coordinate where the guillotines get set up. And long story short, we now have a useless joke of a Twitter.

It was win win for him and the people propping him up, either his delusions that he would be successful with Twitter came true (they didn't) or his likely failure makes all those ghouls happy and he sees indirect benefit from unrelated investment/contracts and someone telling him, "you're the coolest, bro" and him replying, "watch, hey look, are you looking? Look how fast I can run, are you looking? I'm probably the fastest dinner ever actually" [Proceeds to run slow, trip and fall on his face]
