“I do think that for augmented reality, for example, one of the killer use cases is basically going to be you’re going to have glasses and you’re going to have something like EMG on your wrist and you’re going to be able to have a message thread going on when you’re in the middle of a meeting or doing something else and no one else is even going to notice.”

It was striking that Zuckerberg’s “killer use case” of how people might interact with the metaverse involves sending text messages to someone while having a face-to-face conversation with someone else. So, basically, the metaverse is the same as the regular internet, except it’s less obvious that you aren’t paying attention to the person in front of you. I’m just not sure that’s the future we’ve all been promised.

06. Many physical things might soon become holograms 

In his letter, Zuckerberg detailed that creating a space where possibilities are endless would mean that some objects no longer need to be physical.

“Think about how many physical things you have today that could just be holograms in the future,” he said. “Your TV, your perfect work setup with multiple monitors, your board games and more — instead of physical things assembled in factories, they’ll be holograms designed by creators around the world.”

Interacting with these virtual items requires new technical infrastructure, like augmented reality glasses, virtual reality experiences or other types of screens, which is part of Facebook’s development strategy. “This isn’t about spending more time on screens; it’s about making the time we already spend better.”

In addition, Facebook said it plans to sell its devices “at cost or subsidized” to make them available to more people.

“Our hope is that within the next decade, the metaverse will reach a billion people, host hundreds of billions of dollars of digital commerce, and support jobs for millions of creators and developers,” he said.
