If you skip through the series to 'Evolving User + Business Behaviors and the Metaverse' you avoid the hand-waving tech roadmapping and get to how this technology is supposed to change people's lives, and what's described is (mostly) super entertainment-oriented, consumerist, and corporate-crossover-branded to the point of self-parody.
At times I get the vibe that VCs are very keen on having "Fornite but you spend $10,000s more on digital clothing, steroids, vehicles, and housing because you no longer care about the physical world. Oh and the sex workers are now digital. Your 'friends' are digital too, and also computer algorithms." No thanks.
It approaches something like Infinite Jest's Samizdat videotape. Entertainment perfection so engrossing it may literally kill you (if Facebook hasn't made sure you're hooked up to food, water, and sanitation systems).
