You likely know what this means even if you don’t know it in those words. The hype cycle, as defined by Gartner, [which tracks it](https://www.gartner.com/en/chat/gartner-hype-cycle), is that series of cyclical events that happens around nearly all emerging technologies: the breakthrough, the “peak of inflated expectations,” the disillusionment, the period of actual serviceable uses of the tech, and the time when it’s adopted. That pinnacle is the groan time, the moment Justin Bieber drops more than $1 million on an NFT. The moment Facebook buys Oculus. The moment the bodega starts taking bitcoin and you know you’ll never be able to escape this thing, whatever it is.
