It happened: Elon Musk struck a deal to buy Twitter for $44 billion. The billionaire, who is one of the platform’s most popular users, has already hinted at some of the changes he aspires to “unlock” at the company, from making Twitter a platform for “free speech” to making its algorithms open source and purging spam bots. In this conversation, recorded live on Twitter Spaces, Kara Swisher talks with the journalists Casey Newton, Anand Giridharadas and William Cohan about how Elon’s reign will impact the platform and its users — and how the deal could still fall apart.
