Why the Meta chief is betting the company on AI

Highlights from Meta's Q3 2024 earnings call: more than 3.2 billion people now use at least one Meta app every day; Facebook is regaining young adults in the US; Instagram keeps growing globally and launched Teen Accounts; WhatsApp's fastest growth is in the US; and Threads has reached roughly 275 million monthly users with over a million new sign-ups per day - management says it is on track to become the company's next major social app.

The forward-looking nugget: the CEO said Meta will add a whole new category of content to Facebook and Instagram feeds - AI-summarized and AI-curated posts pulled together from multiple sources. Testing is just beginning, but he expects it to become one of the most important applications of Meta's AI over the next several years. AI comment summaries are already visible on some posts in some countries.

For marketers, two implications. First, Threads' growth curve makes it worth a real presence rather than a parked handle. Second, if feeds shift toward AI-curated compilations, the discovery-engine game changes again: being quoted or summarized by the machine may matter as much as being followed. It also raises the trust question - a feed full of synthetic compilations makes transparent, authentic use of AI a brand asset, not just an ethic.
