I think my very simple view of "virtual reality" is: if it isn't as good as the holodeck, it isn't going to work as its proponents want. A bit like self-driving cars, really, in that if they don't work perfectly (and I don't just mean safety) they don't really work in the way people would want.
Though Zuck's vision of his virtual reality of "like reality, but with the shittier parts made shittier" is extra funny. The virtual reality office! Amazing stuff.
