Readers should only take this book as a premier to know what metaverse is about, what technologies are involved, how this can be used to attract users, and business strategies to market their products or services using metaverse. The authors included technologies like blockchain, crypto currency, NFT, VR, AR and boosted they are vital to metaverse platforms, but most of the content is just promoting how they envisage the future ideal implementation of various metaverse, with references to some early days projects in learning and discovering use of metaverse for different business cases. I treat this book as a means in marketing metaverse for the benefits of related metaverse ecosystem vendors.
I have no doubt that metaverse will ultimately become another kind of digital social platform, but I do not share the optimism as the authors ... taking into account a lot of technical advancements (both software and hardware) in the domain of blockchain, crypto and 3D vision reality devices need to be achieved before a good user experience can be vouched for.
With the recent "crypto winter" happening at time of my review of the book, I suspect many will give a second thought on crypto related components in metaverse architecture.
