Zuckerberg reveals AI projects to power Metaverse

Meta founder Mark Zuckerberg has unveiled several ambitious artificial-intelligence projects, describing AI as "the key to unlocking the Metaverse".

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.

And he promised the AI systems driving Meta's virtual worlds would preserve privacy and be transparent and responsible.

Facebook has been investing in AI for the past 10 years and has one of the world's leading experts, Yann LeCun as its head of AI.

In January it announced that it had built a new AI supercomputer that it aims to be the fastest in the world when completed in mid 2022.
