From an economic point of view, the most challenging question is about what will happen when mature lightweight wearables meet high bandwidth wireless infrastructure. The coming sea change is not really about the capability itself, but about what changes in response to that capability.
Going back to historical analogy, we could look at all of the jobs provided by the industry of building and servicing roads and automobiles. Yes, those sectors of the economy are indeed very large.
But those sectors are utterly dwarfed by other economic sectors that are able to exist only because we have roads and automobiles. Everything about our way of life changed as soon as ordinary citizens gained the superpower of individual travel across hundreds or even thousands of miles.
We see the same pattern for other infrastructural innovations. The book industry itself is huge, but is utterly dwarfed by the collective size and variety of industries that have been transformed or downright enabled by the existence of books.
This goes for the Web, for smart phones, and for pretty much anything else that changes the collective interplay between human minds and human bodies. Any serious analysis of the long term economic impact of “the wireless metaverse” needs to be looked at through a similar lens.
