A year ago, Meta made a high-profile move to reshape its artificial intelligence ambitions: Mark Zuckerberg recruited Alexandr Wang to lead a new AI strategy, kicking off what CNBC describes as a "mega spending spree." Twelve months later, according to CNBC, the results are underwhelming — and the burden of selling the vision has fallen back on Zuckerberg himself.

The company has not gone quiet. Meta recently pushed out a wave of product updates designed to put AI front and center across its family of apps, according to Mashable. The moves signal that Meta is still investing heavily in making AI a visible, everyday feature for the billions of people who use Facebook, Instagram, and WhatsApp.

But visible product updates and strategic success are different things. The CNBC report draws a pointed distinction: Wang was brought in to build something transformative, while Zuckerberg is now in the position of having to sell whatever has been built so far.

Wang, the founder of Scale AI, was widely seen as a coup hire — someone with deep credibility in the AI data and infrastructure world. His arrival signaled that Meta was serious about competing at the frontier of AI development, not just integrating off-the-shelf tools into its platforms.

Why it matters: Meta is spending enormous sums on AI at a moment when investors and users are scrutinizing whether Big Tech's AI bets will actually deliver — and right now, one of the industry's most-watched experiments is struggling to show its cards.
