The law of scarcity applies to Elon Musk. However wealthy he is in paper, he’s as impoverished as the rest of us in the time and attention he can devote to his many interests, which is one of the reasons why his offering on Twitter risk of collapsing.
I can think of others. Mr. Musk is not the naïve he finds useful to play. He knows, for commercial as well as political reasons, that Twitter has crossed the river of no return by “moderating” the content that appears on its service – it cannot allow unfettered free expression.
