I think it’s not as isolating as many people initially think just looking at the device—they may not realize you can very plainly see your environment and others can (pretty much) see your eyes with EyeSight (what I generally hear from people who actually gave the feature a fair chance is it’s weird and needs lots of improvement but baseline letting people see the user’s eyes helps and is better than not having it). But even still, there is the isolating aspect of not being able to share what you’re seeing with anyone who is not also wearing a VP. I think in many cases that’s not an issue and is actually desired because most of people’s personal device usage is personal and isn’t supposed to be shared. But there are the times you want to show someone something on your screen. And of course there are the normally shared television type experiences that become isolated on the VP, as well as AR/VR-specific experiences that can only be seen on a headset.
Of course all these wouldn't be issues if everyone had their own VP (or some Apple headset), but that’s not likely to happen for awhile if ever. But for times you want to show someone something you're looking at, there should be ways to do that. If I’m not mistaken, I believe you can live stream your POV or a virtual window to a physical screen? At the very least you can send things via Airdop or some messaging app. Sharing these ways does take an added step or two versus just showing someone your screen. Hopefully Apple made it as easy as possible, but if you’re often needing to show things to people, say at work, either the VP isn't the right device or I suppose one could set up a display to be constantly receiving live stream.
For shared screen television type experiences, I’d say people should just stick to televisions.
As for AR/VR-specific experiences that can only be seen on a headset, if others don’t have their own headset, obviously there is no other option, you either go it alone or go without, just like any other single rider experience (like a massage chair) 🤷♂️. And maybe some will want to go without until they can share it—to each their own.
So I don’t think the VP is particularly isolating unless one chooses to use it that way—ie. alone in place of social experiences. But we do that with all our other personal devices, so it’s essentially just another personal device.
