Yeah, there’s lots of takes on technology that are outlandish, but something like VR/AR HMDs becoming so unobtrusive that they become common seems perfectly viable. Not yet, but I could easily see it being capable of happening in the next century at most, if not far sooner. We aren’t there yet, but it doesn’t seem far off. The issue with current HMDs is mostly just that they’re too heavy to be comfortable, which is a solvable hardware issue.
