Tech companies make a lot of promises about the metaverse, specifically about how we’ll watch movies, hold work meetings, buy virtual real estate and more in these immersive online spaces. Meta — formerly Facebook — and others are investing heavily to create their own territory in the metaverse, which, we’d like to remind you, still doesn’t exist in a complete form. But companies are developing proto-metaverse platforms, and our own Kai Ryssdal, host of “Marketplace” and co-host of “Make Me Smart,” explored one of the more business-oriented spaces, fashioned by a company called Engage. He was guided by Michigan State University professor Rabindra “Robby” Ratan. Marketplace’s Kimberly Adams spoke with Kai about his experience.
