Meta Chief AI Officer Alexandr Wang recently published an open letter outlining the core philosophy behind the Muse AI assistant he spearheaded 鈥?making it possible for every ordinary person to realize their dreams. The letter arrived alongside Muse's strong market performance, further reinforcing outside assessments of the value of the massive $14 billion acquisition.
Muse has gained rapid momentum since launch. According to Sensor Tower data, the app accumulated 2.8 million downloads in its first 12 days on the App Store in the United States and Canada, surpassing ChatGPT's 1.3 million over the same period, and set a U.S. single-day record of 264,000 downloads on September 19. Buoyed by this, Meta's market capitalization increased by approximately $234 billion over the past five trading days.
In the open letter, Wang wrote that most people never voice what they truly want 鈥?not because they lack desire, but because dreams tend to quietly die amid tedious real-world obstacles. He positioned Muse as everyone's "second brain," an "all-purpose manager" capable of understanding half-finished sentences, helping people make plans, send emails, find funding, and clear obstacles.
An Open Letter About "Longing"
In the letter, Wang described the predicament of human dreams with an almost literary touch: "Every unfulfilled longing is a silent tragedy of human potential." He wrote that the world has long been shaped by a small number of "fanatics who somehow turn longing into reality," and that Muse's mission is to enable each of the 8 billion people to truly activate their own agency.
In his vision, Muse is not a wish-granting genie but a pragmatic executor 鈥?one that says, "This is what you've dreamed of your whole life; let's make it happen, and here's how," then takes action.
The letter was published shortly after the conclusion of the Meta Connect 2026 conference. At that event, Meta unveiled Muse Charm 鈥?a standalone pocket device designed specifically for voice interaction 鈥?along with Meta VR glasses weighing only 100 grams and priced at $1,299, and a series of hardware products including the third-generation Ray-Ban Meta Gen 3 smart glasses starting at $249.
From Scale AI to Meta: Returns on a Controversial Acquisition
The way Wang joined Meta was itself dramatic. In 2025, Meta founder Mark Zuckerberg acquired the entire staff of hot AI startup Scale AI for $14.3 billion, with Wang, as Scale AI's founder, reportedly receiving approximately $5 billion personally. At the time, some market observers viewed the deal as an exorbitant price.
Wang is a co-founder of Scale AI, a company focused on providing data annotation services for AI model training that was once one of Silicon Valley's most highly valued AI infrastructure companies. After Meta completed its acquisition of Scale AI in 2025, Wang became Meta's Chief AI Officer, leading the company's AI product strategy.
Tech investor Adam Khoo wrote on the X platform:
"At the time people thought Zuckerberg was crazy to spend $5 billion to hire Alexandr Wang. Now, the new Meta AI products developed under Wang's leadership have added about $200 billion to the company's market cap. Suddenly, spending big to lock down top talent doesn't look so crazy."
The strategic significance of the acquisition is equally profound. The deal effectively reversed the outside impression that Meta was lagging in AI, transforming it from a "chaser" into a "frontrunner."
Camouflage T-Shirt and a $30 Style Philosophy
If Muse is Wang's expression at the product level, then his attire on the Meta Connect 2026 stage unexpectedly became an output of another kind of personal symbol.
That day, Wang took the stage wearing a 1990s-style camouflage T-shirt printed with a deer head pattern, paired with camouflage Crocs and black trousers. After the event, the outfit quickly sparked discussion on X, with some users speculating that the T-shirt was an $800 Herm猫s piece.
Wang promptly stepped in to "clarify," saying the shirt came from a thrift store in Santa Cruz and cost him $30, the Crocs about $60, and his Calvin Klein underwear $5. He characterized the luxury speculation as "defamation."
According to Business Insider, this was not the first time Wang had appeared in similar deer/camouflage style 鈥?he wore comparable outfits in a previous Core Memory interview and at important internal meetings. This "anti-elite" fashion style aligns closely with his online persona on X, where he calls himself a "tweet cannon" and continuously promotes Muse with meme bombardment, and is also seen by some observers as a deliberately constructed brand image: stripping away the sheen of corporate elitism while retaining the chaotic energy of a founder.
