I don't mean this as a criticism of anyone. I do find though that there are types of people (likely including you and I) who feel compelled to move and do things such that our down time is extremely valuable. I do have kids which makes it quite a bit more challenging. I feel motivated on an hourly basis to accomplish things, though - it matters to me to make progress on the things I care about.
There are other people who very much don't care. To them, progress might be watching the next episode of a show, or grinding in some game they love.
I'm fine with either type of person, really. It does explain why what seems like an impossible use of time to us is actually very appealing to others. Why would we be in there when there's a book to read, a concept to learn, people we don't see often enough, etc? And yet, why wouldn't they?
I think the metaverse aims to appeal to us as well eventually; imagine interactive classes on X or Y to help you learn faster with tools that are currently impossible? What if we could save time by seeing loved ones more easily in the metaverse, making more time for those things we want to make progress on? I'm not bullish on that, though. It sounds creepy. I want to hug the people I love, hear them laugh in person, make them nice food. I'm not interested in expediting that facet of my life.
Even now, despite growing up with webcams around I still find FaceTime fairly impersonal and uninteresting. I use it only when I really need to.
