Mark Zuckerberg

In a livestreamed demonstration, he created a basic virtual world - including an island, trees and a beach - using the AI feature Builder Bot.

Mr Zuckerberg also announced a plan to build a universal speech translator.

"The ability to communicate with anyone in any language is a superpower that was dreamt of forever," he said.

Builder Bot was part of Meta's CAIRaoke project to improve AI assistants and allow "AI to see the world from our experience" as people entered virtual reality via headsets or glasses, Mr Zuckerberg said.

Facebook CEO Mark Zuckerberg announced the social media giant will change the name of its holding company to Meta, in a rebrand that comes as the company faces a series of public relations crises.

Zuckerberg revealed the new name at Facebook’s annual AR/VR conference on Thursday, where he outlined the company’s virtual-reality vision for the future.

The billionaire said sorry after an internal technical issue took Facebook, Messenger, Whatsapp and Instagram offline at about 16:00 GMT on Monday.

The scramble to bring it back online eventually succeeded at around 22:00.

But it is likely to increase scrutiny of the social media giant's reach.

For hours, potentially billions of people found themselves without the social media tools they relied upon to keep in touch with friends and family. Others reportedly found they could not access services which required a Facebook login.

A metaverse is an online world where people can game, work and communicate in a virtual environment, often using VR headsets.

The Facebook CEO described it as “an embodied internet where instead of just viewing content - you are in it”.

He told The Verge people shouldn't live through “small, glowing rectangles”.

“That’s not really how people are made to interact,” he said, speaking of reliance on mobile phones.

“A lot of the meetings that we have today, you’re looking at a grid of faces on a screen. That’s not how we process things either.”

"When you're building something like Facebook which is unprecedented in the world," he said on Wednesday, "there are things that you're going to mess up.

"What I think people should hold us accountable for is if we are learning from our mistakes."

As well as being Facebook's chief executive, Mr Zuckerberg is chairman of the company's board. When asked if his position had been discussed, he replied: "Not that I know of!"

The mere possibility that his leadership is in question is a scenario few would have predicted even a month ago.

"Our hearts go out to the family and friends of Robert Godwin Sr," said Mark Zuckerberg near the start of Facebook's annual F8 developers conference.

His social network had been criticised over the amount of time it had taken to take the clip offline.

About an hour before the event got underway, police had revealed that the murder suspect had killed himself.

Steve Stephens had been the subject of a national manhunt.

He justified his decision of not including a dislike button by saying that it can fuel hatred on social media. But, it looks like the Facebook users are going to get the much-awaited dislike button. Well, sort of.

Instead of rolling out the feature for posts in your News Feed, the company is teasing the feature in Facebook Messenger, as reported by TechCrunch.

Now he's focusing on how to stop the world from breaking apart.

In a nearly 6,000 word manifesto published Thursday, Zuckerberg writes candidly about how Facebook's mission for "building a global community" is contrary to the current political trend toward nationalism in the U.S. and abroad.

The billionaire tech mogul had filed a legal case seeking to acquire small pockets of land within his large estate on the island of Kauai.

But his use of the so-called "quiet title" legal system led to criticism from other residents.

He said he had not taken the time to fully understand the process. "It's clear we made a mistake," he said.

Mr Zuckerberg bought a 700-acre estate on the Hawaiian island, where he says his family wish to "put down roots".

However, the estate is littered with a number of small parcels of land called kuleana.

The Facebook (FB, Tech30) CEO and cofounder expressed concern on Friday over Trump's executive orders this week on immigration and refugees.
