By the end of the decade, we’ll agree the Metaverse has arrived* and it will be worth many trillions. The question of exactly when it started and how much revenue it generates will remain uncertain. Before getting to that point, we will exit the current phase of hype and probably enter and then exit another one, too. The hype cycle will be caused by at least three factors: the reality that many companies will over-promise what sort of Metaverse experiences will be possible and when; the difficulty of overcoming key technical barriers; and the fact that, even when those barriers are overcome, it will take time to figure out exactly what companies should build “in the Metaverse.”
