This is an impressive discourse on the current reality of AR, VR and MR. Truth is that this new technologies have much to offer and I personally believe that sooner than we think they will begin to make even greater impact than it is right now. I do not align with skeptics who think there's no future for the technologies. After all, when blockchain tech made its first major breakthrough in bitcoin in 2009 the world did not only not pay attention but people laughed in scorn. Today the world knows better.
Similarly, these technologies will not only take off but will definitely explode and positively impact and enhance our 'real reality', which includes the world of blockchain and cryptocurrency.
