Meta’s Chief AI Officer Alexandr Wang recently shared what surprised him most about working alongside Mark Zuckerberg: his interesting WhatsApp habit. Wang admitted being confused by how quickly Zuckerberg writes long responses while running a tech giant. According to Wang, this impressive skill comes down to one thing - an ability to ruthlessly prioritise every moment.
"I would ask him a question on WhatsApp, and then he would write these really long responses," Wang said during an interview with podcaster David Senra. He added, "I was really confused. I was like, 'How does he have time to write these really long responses?'"
Meta's chief AI officer then explained the conclusion he reached about Zuckerberg’s speedy and long responses. "He'll write a very rigorous, long response very quickly," Wang said, adding, "It's a very impressive skill of his."
The 29-year-old continued that he thinks the only way Zuckerberg can manage everything from his personal life to his professional life is by "ruthlessly prioritising".
"The only way he's able to do that and be a good dad and be a good partner and all this other stuff is to just, like, ruthlessly prioritise."

However, later their communication increased, with not just Zuckerberg advising Wang but also asking his thoughts on Meta’s AI strategies.
In 2025, Meta invested in Scale AI, a company co-founded by Wang. Meta also brought over then-28-year-old CEO Alexandr Wang to play a prominent role in Meta’s artificial intelligence strategy.
"We will deepen the work we do together producing data for AI models and Alexandr Wang will join Meta to work on our superintelligence efforts," Meta said in a 2025 statement.
Alexandr Wang was born to Chinese immigrant physicists in Los Alamos, New Mexico. He dropped out of MIT to co-found Scale AI with Lucy Guo.
