Obviously he is biased but still pretty big statement from a CEO of the most popular game engine.
What AR not-so-obviously does is takes the internet and changes it from a limited access interface, wherein its a technology that has points of access that are limited to terminals that you have to actively access to an interface that you passively interact with.
An interface that you have to seek out, to an interface that seeks you out.
You mean someone that has a personal financial interest in a market growing is talking about how that market might grow. That's not very surprising to hear, don't you think?
It's like stating that computers are bigger than electricity.
My source on this? I worked at one of the first consumer ISPs in Canada, and we regularly had people coming in to sign up because they heard about "this Internet thing" but did not have a computer.
Most people thought we provided one with the service, and some people just didn't understand that you accessed the Internet through a computer.
So, if by "VR" you mean Vive/Rift-level VR, very few people will have a computer already lying around the house that can cut the mustard, even if they bought that computer relatively recently.

I would advance the hypothesis that the prospect of the internet back then seemed much worse compared to dropping a few hundred to have Vive hardware shipped to your door and plugging it in. But the people who built the internet saw what it could be, not the garbage that it was.
And we're still in the beta stages; this stuff only gets better with time.
It's literally doing all of the stuff you mentioned, if you look for it. The blocker is that most people don't have a headset to experience it.
The same thing could be (and was) said about the early internet.
