Why Elon Musk Wants to Change Social Media Forever

Although Elon Musk’s vision for social media change is ambitious, it is faced with a number of basic problems. The most substantial problem is the deep-rooted dominance of established platforms. Meta and Twitter already have established infrastructure, massive bases of users, and billions of dollars, and this acts as a bottleneck for new decentralized platforms’ scalability.
Another issue is regulatory control. Governments everywhere in the world are keen on having social media platforms increasingly under control, primarily content regulation, data protection, and disinformation. Musk’s libertarian ideology of free speech and decentralization are likely going to clash with legal issues in some jurisdictions where more control over web content is the established norm.
Other than the above, the tech feasibility of making a completely decentralized platform with good privacy aspects but still be usable is also not simple. It would require a technological breakthrough to scale decentralized systems to be safe for millions of users.
