Mention in the show
Alexandr Wang is not a participant in the episode; the following are the hosts’ own comments. In Weekly #004’s chapter “Muse：面向普通人的 Personal Agent” (Muse: a personal agent for ordinary people) of the Chinese transcript, Guizang recalls that when Meta bought Scale AI, “many people said Zuckerberg was out of his mind, spending tens of billions of dollars on this,” placing the deal alongside Meta’s market performance after the Muse launch (paragraph). In the chapter “开放生态、资源与商业闭环” (Open ecosystem, resources, and the business loop), Guizang relays earlier Meta coverage criticizing “Alex is an amateur and Zuckerberg is an amateur,” while arguing that “Zuckerberg pushed this forward very decisively, giving any resources asked for” (paragraph and paragraph); Yang Pan asks whether “this Muse is really what Alex is pushing” (paragraph). These remarks are commentary in the show’s context, not statements by Alexandr Wang or Meta.
