The blowup between the president of the United States and the world's richest man has played out on social media in real time, the latest, perhaps ultimate example of how X has become Elon Musk's personal platform, his own reality show where anyone can tune in to watch the mercurial twists and turns of his unpredictable personality. The feud has birthed countless memes, hot takes and speculation, with some X users bringing out the popcorn emojis while rejoicing that the site has returned to its “fun” roots — back when it was called Twitter. While it's not yet clear if the feud will have any permanent effects on X's audience size or advertising business, its owner reposted a meme late Thursday suggesting that, at least for now, it was good for getting active users to tune into the platform.
