Meta CEO Mark Zuckerberg attributed AI improvements to increased time users spent on the company's apps in Q2, despite concerns about "AI slop." The company's recommendation systems improved quality, leading to a 5% increase in time spent on Facebook and 6% on Instagram. Over 3.4 billion people used Meta's "family of apps" daily in June, driving total app revenue to $47.1 billion. Video time spent increased 20% year-over-year.
