On first reading, this sounds pretty good. I agree that we shouldn’t be stuck in our own bubbles of misinformation. But the part Elon gets wrong is the premise that there should even be a “common digital town square” controlled by a single company. I reject that idea.
The common digital “square” should be the entire web, with a diverse set of platforms. There should be common APIs but many communities with their own rules, goals, and business models. Concentrating too much power in only a couple social media companies is what created the mess we’re in. The way out is more platforms, free to make the best decisions for their users knowing that there are options to leave and less lock-in for developers.
