Unlike-in-quality is the same thing, only better. It rarely changes the world, because it's not an infinite value proposition.
Unlike-in-capability, on the other hand, is offering something that literally didn't exist before. It approaches infinite value, because it has the capability to reshape the world into one that requires its existence.
Mobile internet was unlike-in-capability.
I have a very uphill battle convincing myself AR/VR is more than unlike-in-quality.
Maybe the only thing that gets me there is persistence, but the rub of that is that its requirements all require bulky physical configuration and/or isolation.
At its worst, earliest form, a brick cell phone was still portable, and didn't isolate the user from the world around them.
I just think that making the hardware is the toughest challenge. Zuck might be underestimating hardware progress.
If he is right, godspeed, future would be amazing. If not, we'll have net positive experiment out of this and it will accelerate AR/VR hardware dev.
Have you actually tried it? VR in particular demos poorly for people where most of their experience with VR is Google Cardboard. Even VR systems from 5 years ago are dated. You have to try it, especially some notable non-gaming apps

I could see criticizing Mark for betting the entire farm on it.
