Zuck is personally all in on capturing the VR and AR market and making it the next ubiquitous computing platform. They already have their own OS. One fifth of the company is working on VR and AR, 10,000 employees. They are pouring billions into it. Zuck likely understands that he missed the platform boat last time around and doesn't intend to miss the next one. https://www.theverge.com/2021/3/12/22326875/facebook-rea…
I don't think VR will ever take over the world. Too many people get motion sickness from it and I don't think it's only a matter of more pixels/fps. AR... maybe. My personal opinion is the needed electronics (and especially the battery tech) aren't small enough yet, if we're talking AR glasses. If we're talking AR on phones, where's the killer app? Pokemon go?
At that point, the "killer app" becomes the ability to augment your own senses and memory with, for instance, facial recognition that reminds you of who this person is, useful facts you know about them, etc. Or walking or driving directions that are overlaid directly on your view of the actual paths/streets/etc. Or even virtual tours of places—either places you're physically in, or places you're nowhere near, but have a space of comparable size you can walk around in!
The danger, as we saw with Google Glass, is twofold: on the one hand, allowing an unregulated tech titan like Google or Facebook to have access to cameras attached to people's faces; and on the other hand, the fear of allowing anyone to walk around with an always-on (or potentially always-on) camera, whether its recordings ever left the device or not.
