Just to begin - I would recommend reading some about the company "magic leap" they are a pretty mysterious company that has some top notch investors and released their first un secret product recently. They might just be the ones to bring the next breakthrough with their technology, their recent product isn't good enough though, but the technology is there and with time they may become really outstanding.

I would like to give my opinion from a more thoughtful approach and a little less techy one:
I prefer augmented reality, and preferably one that doesn't capture the world and deliver it to the wearer as a picture on the device's screen with added objects but actually let's you see the world and let's people see your eyes.
why? Well - because I fear a world when people lose contact with each other and become enslaved to machines- we could see uprising against this phenomenon when people actually tore down Google glasses off people's faces when they was released to the market. I don't think it will happen today as people got used but the idea is the same- this is a technology which is awesome and helpful and inevitable. But it should come as another layer on top of the world's and not replace it.
In that way we will be able to keep our humanity and real world social contacts whole enjoying the best technology can offer us.

I think that regarding crypto- we might imagine an implamantation of payment methods in this decides that will incorporate crypto support - the people buying such devices want to have new and revolutionary technology so they might just embrace it as a part of the whole ecosystem and so the idea will sip though to broader parts of society with time and wider adoption of the VR/AR Etc...

Thanks for that informative and interesting post!
