The term metaverse seems to be everywhere. Facebook is hiring thousands of engineers in Europe to work on it, while video game companies are outlining their long-term visions for what some consider the next big thing on the internet. Essentially, it’s a world of endless, interconnected virtual communities where people can meet, work and play. You can go to a virtual concert, take a trip online and try on digital clothing. But tech companies still have to figure out how to connect their online platforms.(Laurent Gillieron/Keystone via AP)
