Mark Zuckerberg’s AI hiring spree is costing a lot of money. In response to all this, the company’s valuation increased by over $175 billion, or more than 12 Scale AI deals. ”Our business continues to perform very well, which enables us to invest heavily in our AI efforts,” Zuckerberg said during today’s earnings call. This time, though, he’s playing catch-up in a heated race, not trying to invent a new platform from scratch. The stakes are much higher, even if he’s playing the game with house money.
