Share Play in visionOS, but if someone wants to maintain presence with others, why not just take it off when they're talking to them? If your goal is to watch a movie with others, why not meet up IRL?
Maybe the "cool factor" is gripping. But surely not at this price? Even if they fix the battery and the price in the next couple of versions, I think it'll be hard to convince people to act like it's normal to sit and talk with someone wearing a diving mask in their living room, with 12 different cameras vaguely pointing in their direction, right? Most would feel weirded out with just one camera pointing in their direction.
There are many questions that will be answered in time, like what will happen if that magnetic battery cable gets unplugged unintentionally? Will the whole device turn off? Will they sell bigger batteries or a "wall-plug" option? How will the tracking work in various light conditions? Will Apple make a smaller AR-only option that's actually more like glasses rather than some high-tech gas mask?
I don't know how this will go, it's interesting to witness it though. Many people are glued to their phone and it's difficult to find anyone walking around without earbuds, it's hard to imagine that there was a time when people didn't do that, how did this transformation even happen? It feels like this could be a good opportunity to see how that transformation takes place in real-time.
If this vision of Apple fails, then it fails, as I would expect honestly, unless they manage to sell it to the military somehow.
If it succeeds and becomes a lucrative market, we'll probably see a Google version (sort of Daydream 2.0) and developers will rush to make apps and money. Meta will "pivot" and also make an AR thing. Will most people own one of these in 2035? Will it be normal to have 4 or 5 people sitting around a living room jacked up to Apple's Vision just like how it's (almost) normal now to do the same with phones. That sounds like a lonely and sad future, but at least we would've had an opportunity to witness how this transformation took place.
