If you think your Facebook feed has a lot of video now, just wait.

“In five years, most of [Facebook] will be video,” CEO Mark Zuckerberg said Thursday during the company’s first community town hall, in which he took questions from the public on a range of topics.

He was responding to a question about whether the growing number of photos uploaded to Facebook is putting a drag on its infrastructure. But Facebook’s data centers have it covered, he said. The real challenge is improving the infrastructure to allow for more rich media like video in people’s feeds.

Zuckerberg took questions from a group of users who were invited to its headquarters in Menlo Park, California, and people also submitted questions online.

One of the most popular online question was why Facebook forced users to download its Messenger app for mobile.

The 30-year-old acknowledged not everyone was thrilled with the change.

“Asking everyone in our community to install another app is a big ask,” he said. But Facebook thought it could provide a better, faster messaging product if it split it off from its own app.

“We really believe this is a better experience,” Zuckerberg said.

One user in the audience asked him if Facebook is losing its charm or becoming boring.

The question of Facebook losing its “cool” gets raised from time to time, Zuckerberg said, but “my goal was never to make Facebook cool,” he said. Instead, he wants it to be a helpful service that just works.

Another asked why he always seems wear the same t-shirts and hoodies. Zuckerberg said he wants to spend as much time as possible on things that matter, like how to build products, even if it means thinking less about what he wears.

“Steve Jobs had the same approach,” he said.
