Against most opinions here, I think something like the metaverse can work. The hardware is just not there yet. Once it's a really lightweight device with good enough graphics people will use it.
It's a good few years away - at least a decade or so. It won't happen until the hardware becomes stylish smart glasses instead of a clunky headset.
And it won't be created by Zuckerberg.
For it to really become the next computing model it has to intuitively understand user-intend which has now become possible with generative AI. AR + generativeAI moves the interaction model from imperative to declarative, users will describe what they want (give me 10 slides with red backgrounds) instead of how to do it. imo generativeAI and LLMs will be primarily seen as a UX revolution (in light of AR)
