Elon Musk, CEO of Tesla and SpaceX, has announced that Twitter's iconic blue bird logo will be replaced with an "X" later today. This is the latest move since Musk purchased the social media platform for $44 billion last year, and follows the launch of xAI, a startup that seeks to understand the true nature of the universe. Twitter users are sure to be excited by the logo switch, and it will be interesting to see what other changes Musk has in store for the platform.
